#200    Found in my home (on the floor, under the edge of the carpet, near my bed), downtown Toronto.   G.
        ~~~~~~~~~~~~~~~~~~ 
Appears to be the larva (caterpillar) of a small moth. One possibility is that it is the larva of the webbing clothes moth (see http://www.insectslimited.com/wcmcl.gif ). In this case, you should find evidence of feeding – including some webbing – on woolen items (including the carpet) in the vicinity of where you found it. If no damage associated with additional specimens is found, your critter likely simply is an accidental intruder of no real consequence.  Ed Saugstad, retired entomologist.  Sinks Grove, WV
#199.   Hi:  We live in mid-France, Creuse, and today picked up a piece of wood in one of our sheds and underneath were these giant grubs. I didn't want to kill them if they are not going to eat our old farmhouse which is full of oakwood. Be pleased to have any comments.  Thanks.  Juliet Scanlan
          ~~~~~~~~~~~~~~~~~ 

These are larvae (grubs) of large scarab beetles (Coleoptera: Scarabaeidae). The larvae of some species of this family, as well as those of some stag beetles (Coleoptera: Lucanidae) feed on decaying wood (including that found in cavities in living trees), but are no threat to sound wood. Ed Saugstad, retired entomologist.  Sinks Grove, WV

See

#198  I found this little guy just a short way from my home here in Northern Newfoundland Canada. 
I have lived here all my live and this is the first one I have ever seen, what is it.  Preston Johnson

This is the larva of a sphinx moth (Lepidoptera: Sphingidae). These larvae sometimes are called ‘horntails’ because of the fearsome-looking but harmless spine-like projection on their tail end.  Ed Saugstad, retired entomologist.  Sinks Grove, WV 
#197  This spider was on my covered deck in Southeastern Michigan earlier today. I don't know whether it came from the ground below or from the roof up above. I used the zoom on my digital camera in the second photo. I just want to know if the spider is poisonous or not. Thanks for your time and attention. Any help you can give will be GREATLY appreciated. Barb Cox.
           ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is a jumping spider (family Salticidae). These spiders are active hunters with excellent eyesight. They do not spin a capture web, but often use a ‘lifeline’ when they jump. Like virtually all true spiders, they are venomous, but only a very few species are large enough to be able to penetrate human skin. None are known to be truly dangerous, but a couple of United States species can deliver a painful bite if mishandled (they are not aggressive, and will not bite unprovoked).  See
http://www.fact-index.com/j/ju/jumping_spider.html for more details on these fascinating creatures.   Ed Saugstad, retired entomologist.  Sinks Grove, WV

#196  Can't say I have an idea what this is... although it seems to have some similarities to the glassy wing sharpshooter.  I'm from Stockton, California and it was found in my back yard.  Any help is appreciated.  Thank you.  MARC

This is a bee, but I cannot be certain of the family. It might be a Megachilid, commonly known as leafcutter bees.

Ed Saugstad, retired entomologistSinks Grove, WV

It has probably been awhile since you posted your question #196 but I believe that is a Ambush Bug is the name no it is not a bee.  D. A. 
  

No offense to D.A., but that is definitely not an Ambush bug.  Ed is correct that it is a bee, and I agree that it is of Megachilidae.  Although making an ID from the picture is difficult, I have to say it looks very much like a Megachile maritima.  J.D. Roberts, Entomologist
 
 (New posting) 
It occurred to me that this could very likely be a sexually dimorphic male of the Xylocopa genus (Carpenter bee).  After further research, I think it could possibly be Xylocopa brasilianorum, X. varipunctata (http://www.insectaculture.com/xvaripunctata.htm), or X. frontalis (http://zoo.bio.ufpr.br/hymenoptera/maracuja_visitantes.htm).

#195  I live in Florida - These bugs are climbing my walls in my home - I think its some sort of tick but I'm not for sure. We have been flushing them down the toilet or popping them (which then blood squirts out) They are light in color - maybe a light grayish, they are not black - It makes me nervous and I'm unable to go to sleep tonight - I just found them tonight and I'm washing my sheets as we speak! Can you please help me identify these very tiny little creatures - I need to know what I need to do to get rid of them and fast!  Thanks,  D.W.
~~~~~~~~~~~~~~~~~~~~~
Although i am not sure my best guess would be that you have a case of bedbugs... they most often prefer to feed on human blood but im not sure how to get rid of them you could probably find some information on this website.. they often live in and under beds cleaning that area very good would be a good start.  Joshua.

#194  Hi:  I live in Woodstock Ontario rural area and these bugs have invaded my property by the thousands. They started at the end of July and fly around between 3 pm to 6 pm, they are attracted to beer, wine and vinegar. There size varies from !/8 - 1/4 of an inch in length. Sitting outside during these hours is imposable. If someone can tell what they are and how to control them, I would be very grateful.  Thanks Tom
     ~~~~~~~~~~~~~~~~~~~~~~   

This appears to be a picnic beetle (Glischrochilus quadrisignatus; Coleoptera: Nitidulidae) Other members of this family collectively are known as sap beetles. They often are pests in gardens where they feed on ripe fruits (such as strawberries) and some vegetables (particularly sweet corn that has been damaged by earworms or corn borers).  They appear attracted to the chemicals given off by ripening or fermenting fruit/vegetable matter. See http://ohioline.osu.edu/hyg-fact/2000/2047.html for a fact sheet that includes some control recommendations. Please bear in mind that they are extremely common in the general environment, and complete control likely is impossible.   Ed Saugstad, retired entomologistSinks Grove, WV

#193  hello, from Brewster, NY, these bees always come around when there is food....what are they?
    ~~~~~~~~~~~~~~~~~~~~~~
This is not a bee.   It is a Yellowjacket wasp.  They are a real nuisance around food in the late summer.
See this page for more information and help:

#192    Here is a picture of an insect that was brought to me for identification.  From the mouth parts and antenna I believe that it is a moth of some type, but the transparent wings are throwing me off. The edges of all four wings are scaled. It was caught in south Alabama following hurricane Ivan.   Rad.
        ~~~~~~~~~~~~~~~~~~~~~~~~~~ 

This appears to be clear-winged moth (Lepidoptera: Sesiidae). The adult moths often are brightly colored, and sometimes mimic wasps in appearance and flight behavior. The larvae are wood-borers, and some species are important pests on trees and shrubs.

Ed Saugstad, retired entomologistSinks Grove, WV      
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This moth is the Scarlet-Bodied Wasp Moth (Cosmosoma myrodora), it belongs to the family Arctiidae subfamily Syntominae. The link leads to a picture and a distribution map.

Martin Hauser,  Department of Entomology, University of Illinois
                                         ~~~~~~~~~~~~~~~~~~~~~~~

Corrigendum to Number 192 – My thanks to Dr. Hauser for correcting my careless mistake. I had totally forgotten about Synotomids, but the shape of the abdomen alone on this specimen should have warned me off Sesiidae. 

Ed Saugstad, retired entomologist,  Sinks Grove, WV

#191    We have about half a dozen wicked looking black spiders drown in our pool per week. They are mostly black with a large body where the legs are attached and a relatively small light brown abdomen (back bit). I know it has 8 legs but the front arm things are very long and sturdy giving the appearance of having 10 legs. They appear to have two eyes on raised bumps close to the front (I know they have 8). Finally they have very sharp and relatively long fangs 2mm or so. The spiders are about the size of a toonie and look like pictures of the Sydney funnel web and trapdoor spider. I know the Sydney funnel web is indigenous to Australia but it is a similar shape.
I can send a picture if it helps. I am not too concerned about them in the pool, they are dead, it is the live ones I am concerned about since we have a large yard and two young children.   Ian., 
Tsawwassen, British Columbia.
     ~~~~~~~~~~~~~~~~~~~~~~~ 

This is a male spider (you can tell by the enlarged pedipalps that look another pair of legs at the front). Because you could see two  relatively large eyes, I suspect that it most likely is a wolf spider (see http://www.accessexcellence.org/LC/SS/wolf_spider/small_lycosid_face.gif), in which case it is unlikely to be of human health concern. In fact, with the exception of the hobo spider (an introduced species now found in the northwestern United States and adjacent areas of Canada), I am not aware of any large spider in Canada that is of medical importance. Like the Australian funnel web spiders, the male hobo spider is more dangerous than the female. A large adult male hobo spider can have a leg span up to 2.5” – see

#190     Photo was taken 09/19/04 in Clinton, TN. Caterpillar is about 4" long and about 3/4" diameter. It was found on a Datura stem. What are the white nubs it is covered with?  Thanks.  Deborah
          ~~~~~~~~~~~~~~~~~~~~~~~
I believe what you are seeing are the eggs of a parasitic fly (order diptera) that uses the caterpillar as a live host on which to lay its eggs. Upon hatching the larvae will feed on the caterpillar eventually killing it.   Bob.
          ~~~~~~~~~~~~~~~~~~~~~~~
The caterpillar in question (a large sphingid, likely a tomato hornworm), has been parasitized by a small braconid wasp (Apanteles sp.). The white objects are the cocoons spun by the wasp larvae after they emerge from the host’s body. The large number of cocoons is the result of a phenomenon called polyembryony, in which a single egg develops into two or more (sometimes hundreds) genetically identical individuals.  Ed Saugstad, retired entomologist Sinks Grove, WV
  #189.   Hello,  Please help me identify this horrible flying bug. It's nearly 1" in length and after I captured it in our rec room, I noticed it covered with red spider mites. It's the 3rd one we've found. Should we just move residence or is it harmless? Thank you.  Lynn D, 
~~~~~~~~~~~~~~~~~~~~~~~~
This is a carrion beetle (Coleoptera: Silphidae) in the genus Nicrophorus. Also known as Sexton beetles or burying beetles, these interesting creatures perform a useful (by human standards) role in nature by consuming carcasses of small dead birds and animals. They are becoming increasingly scarce in the United States, and at least one species is considered federally endangered (see http://www.northern.edu/natsource/ENDANG1/Buryin1.htm  for details). As a child 50 years ago, I saw them quite frequently on our farm, but now, to find one is a real treat. By the way, the mites you see on the beetle apparently help keep the beetle’s food supply safe by feeding on fly eggs and also clean bacteria from the beetle itself. They ‘hitch a ride’ (phoresy) on the beetle to ensure that they arrive at the food site.  Ed Saugstad, retired entomologist.   Sinks Grove, WV
#188.   Hello,  This bug bit me on the back of the neck. Found in New Berlin, Wisconsin on 09/16/04.  Can you help me to identify it?  Thanks,  Tim
~~~~~~~~~~~~~~~~~~~~~~~~~
Appears to be an assassin bug (Hemiptera Reduviidae). Most species are predaceous on other arthropods, but, except for some Latin American species that transmit Chagas' disease, mainly are harmless to humans. See also number 182.

#187.  I found this spider while I was mowing my lawn. I live in Buchanan, MI. It was on my stone wall of my house... It is about the size of a closed matchbox (like you would pick up at a bar or a casino). Just curious as to what it may be... I looked into it a bit, and it looks like a "house spider"? Anyone know what it is, and if it's anything to worry about? It was near where my 2 year old likes to play...Thanks.  Tom
 #186.  We have found several of these in our home.  We live in central NC.  They are 1/2 inch to 1 inch long.  What are they? Richard
~~~~~~~~~~~~~~~~~~~~~~~~

Definitely a beetle larva; most likely a Carabid (ground beetle) or close relative. Carabids comprise a very large family of beetles, most members of which are predaceous on other small arthropods.  Ed Saugstad, retired entomologist.   Sinks Grove, WV

 #185 This insect has the shape of a fly, is about 2 cm long and maybe 2.5 cm across. The design on its wings is striking and probably makes it easily identifiable to someone trained to do so. I found it in late afternoon, in a meadow near Kingston Ontario which is on the north shore of the St. Lawrence River. It flew from flower to flower, apparently feeding. Many thanks to Sandra C. and Martin Hauser for helping me with an earlier identification.  Steven Burke
~~~~~~~~~~~~~~~~~~~~~~

Number 185 – Appears to be a large bee fly (Diptera: Bombyliidae). The adults often are found on or around flowers; the larvae are parasitic on other insects, including caterpillars and the egg cases of grasshoppers. See http://vidal.med.puc.cl/insectos/BombyliidaeSp2.jpg for an image.  Ed Saugstad, retired entomologist.  Sinks Grove,

#184.  Hi - We found this guy crawling around our design studio this morning. Our studio is in a very wooded overgrown area in the hills of Los Angeles, close to downtown. This guy is about 7/8" long. Hope you can help us. We have a pool going to see who is right.
Thank you.  Glenn

This is a nasty house centipede... I've been having a problem with those critters on the third floor of my house because I'm pregnant and cant use pesticides, but I've been told they become less of a problem if you use a dehumidifier because they hate dry places. Barb
~~~~~~~~~~~~~~~~~~~~

This is a house centipede (Scutigera coleoptrata), common throughout much of the United States and Canada. They often are found indoors, especially in basements and bathrooms. They are much faster movers than most centipedes, and are predators on many other arthropods. See http://www.ipm.iastate.edu/ipm/iiin/housece.html for a fact sheet.

 #183  This interesting looking spider has made quite a large web outside of our home in the back of our house.  It has been there for about a week now.  It's body is about the size of a dime and the picture is obviously from its underside.  We live in the Hudson Valley in New York State.  Do you have any idea what type of spider this is?  Thanks.
~~~~~~~~~~~~~~~~~~~~~~~~

This is an orb weaver spider (Araneida: Araneidae). These spiders usually are noticed in late summer/early autumn as the females fatten up prior to depositing their egg masses. Many species feature banded legs such as are seen in your photo.  Ed Saugstad, retired entomologist.  Sinks Grove, WV

 #182  Hello.  We've found 2 of these bugs in our home so far.  they resemble cockroaches with an elongated snout.  They fly.  Do you have any idea what they are?  We have found them upstairs in our spare bedroom and our computer room in the window sill.  They are apx 3/4 inch long.  These were the best pictures that I could take. 
Thank you very much.  I have looked on the 'net to get an idea as I live in the lower mainland of BC.  We have not found any in any food areas.  We keep our kitchen clean.  They have been found during the daytime.  Thank you very very much.  Heather Lee.

#182...Looks like a "Kissing Bug". Hope you kept it for I.D.
reference! These can be hazardous to your health. Better do your research on this one.  Randy.

Appears to be an assassin bug (Hemiptera: Reduviidae). These are predaceous on a wide variety of other arthropods. Some larger specimens can deliver a painful ‘bite’ if mishandled, but species in your area are otherwise harmless to humans.

....looks like a "Western Conifer Seed Bug". I have recently seen more and more of these over the years. They seem to show up early in the fall. (Toronto,Ontario) Check out these sites, they have great pictures!  Carter
 #181  Hi there,  About 3 months ago these little brown bugs started showing up in our bathroom and kitchen.  We also had a baby 3 months ago and, of course, have had lots of new stuff coming into the house:  furniture, clothing, etc.  I suspect they came in on something, or maybe in the cardboard boxes things were packed in.  
One night we killed 20 of these things in the bathroom.  Usually we only find 5-6 per night.  The bathroom is directly above the kitchen and we think they are following the pipes, though when I startle them at night they run under the door frame in the bathroom.  We have seen the odd one in other parts of the house but suspect our cats are catching them and playing with them.  They are very small.  At first we could barely see them.  Now they are about a quarter of an inch at most.  They are medium brown with long attenae and move quickly and erratically.  They do not stay along the walls but move across the floor in zig zags and circles.  They only come out late at night and are initially 'frozen' by light but then start moving very fast.  They can be easily crushed with a paper towel or piece of toilet paper. 
I suspect they are German cockroaches, but they do not behave anything like the big black cockroaches I have encountered in apartments in the past.  They have been ignoring the cockroach bait stations we put out and have not shown any interest in garbage cans or any food left out in the kitchen.  My husband and I have started covering everything and taking away the cats food and water at night and putting the plugs in the sink drains to ensure that these bugs don't have any obvious source of food or water.  Things are not getting worse, but we aren't getting rid of them, either. 
Can anyone tell me what these are and how to get rid of them?  I found one in the baby's nursery (next to the bathroom) the other night and that was the last straw for me!  Thanks.  Angela
     ~~~~~~~~~~~~~~~~~~~~~~~~~~~~
You likely are correct in believing that you have German cockroaches (Blattella germanica), although because of the blurriness of the photo, there is a remote possibility that they might be brown-banded cockroaches (Supella longipalpa), which also are small and fast-moving. See http://pested.unl.edu/bbroa.jpg  for links to images of both species. Also see http://ohioline.osu.edu/hyg-fact/2000/2099.html for a fact sheet that includes control recommendations.  Ed Saugstad, retired entomologist Sinks Grove, WV
#180   These flying insects are all over our yards and came out all at once in the past 3 weeks.
What are they? are they harmful?  Thanks for your help.  Paul
              ~~~~~~~~~~~~~~~~~~
Crane Fly. These Daddy long legs are not much of a problem, except they will lay eggs in your lawn which will develop into leatherjacket larva.  In large numbers the leatherjacket larva can kill large areas of the grass by eating the roots. Unfortunately in many parts of Canada it is against the law to use pesticides to control this pest. The larva  develop into Crane flies in the late summer and are quite noticeable because of their size. More information on this web page:  http://www.hdra.org.uk/factsheets/pc13.htm
                                              ~~~~~~~~~~~~~~~~~~~~
A follow-up to the answer already posted: Although the larvae of a few species of crane flies (largely of European origin) can indeed damage roots of plants including many grasses and some young conifers
(see http://www.forestry.ubc.ca/fetch21/FRST308/lab3/tipula_paludosa/leather.html ), the larvae of most species are detritus feeders in aquatic or semi-aquatic environments, and those of a few aquatic species are predaceous on other arthropods. Because so many other insects can cause damage patterns very similar to that attributed to leatherjackets, some caution should be exercised in determining the culprit responsible. For more general information on this family of insects, see

 #179 I've lived in Miami, Florida in the US all my life. After purchasing a new home recently, we've been finding these nasty little bugs all over the place outside. They seem fond of our basil plant, mango tree and are usually clinging to our walls outside. The bug is approximately 1 cm long and flies. I've been baffled because I've never seen them before and have not been able to find them on the net. Any clue?
And yes, I put it in a ziploc bag :)  Thanks, Juan

A snout beetle (Coleoptera: Curculionoidea; some species are called billbugs). Snout beetles form a very large complex of beetles in several families, and many species are of economic importance. I am no expert in this group, and so, although it bears a resemblance to Artipus floridanus (see http://www.doacs.state.fl.us/pi/enpp/ento/images/artipus.jpg for an image), I suggest that you take some specimens to the Miami/Dade County office of Florida’s Cooperative Extension Service for assistance in identification and control measures if necessary. See http://miami-dade.ifas.ufl.edu/  for contact information.  Ed Saugstad, retired entomologist, Sinks Grove, WV
  #178  Can someone tell me what this beetle is? I live in Greely, Ontario, Canada, near a sub watershed, so I suspect that the bug came from the open windows. They tend to like lurking the in carpet, but it does not look like a carpet beetle.  It is about 1/4 inch long and does not seem to like to fly.  Pauline

This is a larder beetle (Dermestes lardarius; Coleoptera: Dermestidae). They are cosmopolitan in distribution, and will feed on just about anything that contains protein. In the days before home refrigerators were common, these beetles often infested dried meats. Today, they can still be found in many homes, but usually are not a serious pest. We still find the occasional specimen in our house.

  #175  Hi.  We found this one at the swing set, in our backyard. We found a second one at the other end of the same swing set. We did not notice any food in either (large) webs. The bodies are approximately 1 1/2 cm, with legs 3-4 cm across. We are concerned because we have curious young children and dogs. We live in rural Quebec, 40 minutes northwest of Quebec City. It is middle September, 2004. What is it and more important, could it be poisonous? Thanks.   Sincerely, The Lauckner Family

An orb-weaving spider (Araneae: Araneidae), a very large family of spiders. Although some can get rather large, none are known to have a particularly potent venom, and most have ‘jaws’ (chelicerae) that are quite small for the animal’s size. However, as in most instances of stinging/biting arthropods, some individuals may be hypersensitive and could suffer an allergic reaction to a bite. Ed Saugstad, retired entomologist,  Sinks Grove, WV
  #174  Hi there, we have found seven of these rather large slugs in our garden in Port Elgin, Ontario. The largest measured over six inches and appears to resemble "tiger' slugs found in British Columbia. Have these slugs migrated from B.C. and more importantly will they survive the winter conditions found around Lake Huron ? Thanks Len.
     ~~~~~~~~~~~~~~~~~~~
  I’m no expert on gastropods, but this specimen bears a strong resemblance to Limax maximus, sometimes known as the giant garden slug, leopard slug, or spotted garden slug. This is a species introduced from Europe, and now widely distributed in North America.

Appears to be a very dead and desiccated small centipede, possible an immature house centipede, Scutigera coleoptrata. These are commonly found in basements of houses. These basically are harmless to humans, but are general predators on a wide variety of small insects and other arthropods. Ed Saugstad, retired entomologistSinks Grove, WV
#172  Here is a caterpillar we found boring into a (pressure-treated) post on our deck in Massachusetts, US (September, 2004). Any ideas on identity?   David Larson,  Bradford, MA
     ~~~~~~~~~~~~~~~~~~~~~~
Appears to be the larva of a wood-boring wasp (Hymenoptera: Siricidae). They may be distinguished from caterpillars by the presence of prolegs on the first two abdominal segments. Although widely distributed, these insects never seem to get abundant enough to be serious pests. Ed Saugstad, retired entomologistSinks Grove, WV
#171  Hi: I found this dead thorax (fly) today (Aug_25_04)in the backyard of our home in Acton, ON. It is very big, the length is ~2.25''. I have never seen such a big "fly" before. It would be good to know how this insect behaves, what it likes and dislikes, etc. Thanks, Will

This is an annual cicada, also called Dog-day cicada. These insects suck on trees (you can see their long proboscis on the underside), but they can not sting humans. They are producing the constant buzzing sound you hear outside your house in the evening and during the night.

  #170  Hi: This beautiful beetle was flying around the garden lamp at 10:00 PM. In the air it seemed to be bigger, but landed, it was ~1 inch long. When it flied, it has created noise, which you would not much expect from small bug. So, my dog noticed it first. The beetle landed on the ivy, where it was photographed. I was just curious, what is this bug, and whether it’s harmless to humans/animals. Thank you,
Will,  Acton, Ontario

#168  we found this spider in our basement.  it was of significant size and we started searching to see what it was.  the only spider we can find that resembles it is a brown recluse but it was much bigger than the average size reputed for the brown recluse.  If it is a brown recluse, what is our next step.  we killed it but do we need to have a pest control place come in and spray??  thanks for your help.   Ange,  Kingston, Ontario

Difficult to tell from the photo, but definitely a male (enlarged palps) spider. If it was quite large, it most likely was a wolf spider – these often wander into buildings in rural/suburban areas. In any case, it is not anything to be concerned about from a human health standpoint. Ed Saugstad, retired entomologist,  Sinks Grove, WV
  #167  First, you have a great site. I'm in SW Ohio, and these guys seem to like giant marigolds. Been here over 30 years, never seen them before. About 1/2 to 3/4 inch long. Fly like a firefly, but doesn't look like fireflies I have caught. Thank you for any info...JIM

  #166  Hi, we live in Vancouver, Wa. (AD not BC) and we found this little creature wondering up our driveway. It has a nice large pinchers on the front and it appears to want to sting from the rear when it is trapped. My neighbor was pinched through his shirt on the tedious struggle to capture this 1 inch nightmare. Can you help us I.D. this guy so we can know if my neighbor has long to live or not? We know that the bug bites, but can it sting? Bob
~~~~~~~~~~~~~~~~~~~~~~~~~
This is a Rove beetle (Family Staphylinidae). So your neighbor will live because they can not sting. They just try to pretend that they are dangerous (and it worked). They can fly (they fold their wings with the help of their abdomen) and they are often predators of smaller insects. Often they come to road kill or dung and feed on fly maggots. The family is very diverse with thousands of species in North America.   http://tolweb.org/tree?group=Staphylinidae&contgroup=Staphylinoidea

    #165  Hello, I live in central Wisconsin. I saw a dead bird outside my patio door. But then it started to move. It freaked me out for a bit until I saw about 3 or 4 of these bugs come out from under it. It's black with orange strips down it;s back as you can see.  Kevin.

This is a carrion beetle (family Silphidae) of the genus Necrophorus (also spelled Nicrophorus). These beetles are very useful because they get rid of dead animals, which they bury in the ground. They are "good parents" because they feed and guard their offspring. Some of these beetles are even endangered.  http://www.unk.edu/acad/biology/hoback/carrion_beetles/Nicrophorus1.htm

  #164  Hi my name is Nick and I live in Thunder Bay Ontario and found this guy hanging off an old clothesline door on the side of my house and I am dying to know what kind he is and any cool facts about it. With the legs spread out I would say it was at least the size of a twoonie($2 coin), any help would be great. It has a weird white cross on its back and color are reds blacks white orange yellow.

# 163.  I just noticed a  strange  fly on the  hood of my car while parked in the driveway, it was all black about th size of a small dragonfly but with only one set of wings it looked a lot like a large mosquito but all black it had a long black tail that was thin and round in about 4 sections and when i approached it it seemed to go on the defensive and put its tail in the air like a scorpion would do to sting, there didn't seem to be a stinger on the tail but i didn't want to get to close to it to find out i did get some digital pictures of it, i guess i am wondering if this insect is dangerous to my kids i guess, and what type it is.  This is not a bug i have ever seen before specially in Nova Scotia.  Thanks. Dale.   Shearwater, Nova Scotia

#160  I found these all on the ground and on a dead limb underneath a golden rain tree in my front yard in  Alabama.  Please tell me what they are and how to get rid of them with nontoxic substances.  Thanks.
                                       ~~~~~~~~~~~~~~~~
I call them love bugs because they are always mating.  I too have thousands of them eating the pods of the golden rain tree.  I think they are some kind of box elder beetle.  Good luck trying to get rid of them.  Clean up the pods, get rid of the golden rain trees, if you let two live, you'll have 2000.  I live in Oklahoma and have been trying for several years.

# 158  Hello,  First, thank you for such a wonderful web site. I found the various pictures to be fascinating. I stumbled onto your site while trying to figure out the identity of some little insects that have seemingly appeared over the past few weeks and are now starting to get out of control. I have seen a few hundred throughout my house in about 3 weeks.  I live on Long Island, NY State (just east of Manhattan)  about 1-2 miles from the ocean.
It seems like there are 2 different types but I think the smaller ones are just younger versions. They fly although they do seem to prefer crawling. The smaller ones are more brownish (almost rust colored) than the larger ones which are black. The smaller ones look like they have 2 sections to them, a body and a head. But, if you move the paper or bag they are on, the "head" part either rolls under the body or it somehow retracts into the body.When the "head" part disappears, the remaining "body" part just looks like a little brown oval nub. The black ones also have 2 sections but don't seem to 'retract' their heads.
The smaller brownish ones are about an eighth inch long lengthwise. The black ones are maybe a quarter inch. We have a 10 month old in the house and although I am sure they are not dangerous or poisonous, I still don't want them on her or in her food. What do they eat so perhaps I can put out bait to draw them in to one central place?  How can I get rid of them? Will a regular "room-fogger" be enough to take care of them?  Thanks,  Mike

Although I am not sure of the name of this bug, I had the exact same problem in my house. These insects tend to congregate and build “nests” in old grain-based environments, for example: an open cream-of-wheat box, a box of cereal that has fallen behind the refrigerator (as was my case), open containers of flour, etc.  I suggest cleaning out EVERY cabinet and looking into every box of grain, cereal, etc. that you have in the house. As well as pulling out your oven, fridge, and other appliances or furniture that may be hiding old grain or grain-based food items.  In my case, I found a half-empty bag of cereal that had fallen behind the fridge, as well as an open box of wheat cereal in a cupboard – both items contained HUNDREDS of these little brown and black bugs, along with their eggs and extended families!  After throwing away the offending food sanctuaries, the problem went away!  Cheers,  Mark

  #155  Hi,  I'm from Dieppe, New Brunswick, Canada. I found this huge spider in my backyard. I never seen a spider like this and this big in this area. Any idea what type it is and if it is dangerous. To size it, the spacing between the planks on the picture is 1 1/2 inches.   Thanks  Yvon Hache

Argiope aurantia (Araneae: Araneidae). This beautiful spider goes by many common names, including black-and-yellow argiope, golden orb weaver, writing spider, and yellow argiope. They usually are not noticed until late in the summer when they are nearing the end of their growth. They pose no threat to humans, and are among the few creatures that I have witnessed eating Japanese beetles. Ed Saugstad, retired entomologist Sinks Grove, WV

 #153 This bug is all over a tree in my yard in Arkansas.  Virgil

When I first saw this photo I thought it was a possible Coreidae species nymph.  It isn't, however, it is a true bug (Heteroptera) in the family Rhopalidae.  These are nymphs of one the scentless plant bugs, specifically Niesthrea louisianica.  These are not serious economic pests but can be a pest to ornamentals such as hibiscus.  They have actually been studied and used to help control the weed, velvetleaf.  This is a very interesting submission.  Great photo.  More photos here - http://ipm.ncsu.edu/current_ipm/98PestNews/98News19/niesthre.jpg  & http://bugguide.net/node/view/34545/bgpage    J.D.

#152  I live in New York City and have seen these little flying bugs (.5 cm) all over my apartment in great abundance. Light doesn't seem to bother them, so I usually see them during the day.

The critters in question are male ants. As you can see they cannot bite because of poor jaws or sting. They were simply trying to get out to a mating flight where they mate with winged queens. They should be no threat at all. :)   Bob

#150  I live in the state of Delaware located on the east coast in U.S.A.  I was out side my house washing my truck when my wife noticed this strange looking bug/insect on our driveway. After she pointed in out to me, I immediately grabbed my camera and took several pictures of it.  I have never seen a bug like this in my life. It was approximately two inches long and close to 3/8th of an inch wide.  I then went back into the house to get a jar to try and catch it, but when I came back; my wife said that it had flown away. Any idea what it may have been?  Edward.

Thank you very much. I was the one that sent in the picture #150. I never thought that there would be an answer or let alone a name.  Now I have that urge to actually go out and look for more unusual insect or bugs.

#149   Hi -  Something very similar to #113.  Found in a head of lettuce in Duncan on Vancouver Island, this guy measures about 1 1/4" to 1 1/2" long, makes a small squeaky/hiss sound, and his legs can really grab hold with tiny hooks.  I think he just let out a smell too. I haven't been able to identify him as any kind of Stick beetle so far, or cleoptera, but I think he is from this genus. Hope we can identify this guy.   Maureen and Rob
             ~~~~~~~~~~~~~~~~~~~
You are correct about this insect being very similar to #113, the ten-lined June Beetle (Polyphylla decemlineata; Coleoptera: Scarabaeidae). If it is not the same species, it is an extremely close relative.

#148  I just found this creature down the road from my house (Richmond BC). Is it a type of earwig? 
Shula.  Richmond, BC.

  Definitely NOT an earwig, but photo not clear enough for a definitive identification if the lateral projections are legs, it would be a small centipede, but if they are spines/setae, it most likely is the larva of a beetle. Ed Saugstad, retired entomologist, Sinks Grove, WV 
 
 #147  Hi,  As I was walking from my car to my house, I noticed this, for lack of a better term, "thing" on the ground. It appeared to be dying, possibly from getting run over. I tried researching the "thing" and in about an hour, got nowhere. I was extremely surprised to see that this "thing" was measured at just over 2" long and just about 1" wide. I live in southwestern Ohio, near Cincinnati. I am fascinated by this "thing" and would like to know exactly what it is. I know I'm not in Canada, but would greatly appreciate a response anyway.  Thanks,  Paul

  This is a larva of a moth in the family Citheroniidae (Royal or Regal moths- see http://www.stetson.edu/~pmay/bugs/saturniid%201.jpg ). From the photo, it is difficult to tell whether it died from being squished, or to have died during the process of molting the last larval skin to become a pupa. Although fearsome in appearance, they are completely harmless. Ed Saugstad, retired entomologist, Sinks Grove, WV

#146   We've seen quite a few of these moths in our Victoria, B.C. apartment over the past few days of August.  They're photophilic, I think, as they often flutter around lamps.  They're distinctly two-toned: half of the wing (the end closest to the head) is light beige, while the other end of the wing is a darker brown.   This moth was photographed resting on our kitchen ceiling.  It's probably a commonplace critter, but I would appreciate identification, as we're wondering if it's the kind of moth whose larva eats fabric or food!   Thank you, Julia

- Indian meal moth maybe.  I had some in my kitchen once that apparently came from some food source in a bag - My dog's food?  Flour?  I can't remember what the source was if I knew.  Cary
                                 ~~~~~~~~~~~~~~~~~~~~~~~~~~~
This is Julia replying to Cary's identification. You're right, it was indeed an Indian meal moth - thank you!  And we located the source of the infestation:  a bag of peanuts that had been left open in a cupboard.  Needless to say, those peanuts are history.  We've done some additional cleaning up; so now, aside from the occasional straggler, looks like the moths are gone.  We'll be more careful of our stored dried goods in future.  Thanks again for your assistance.
#146.  Hello!  This is not a pest as far as I know. We live in Bridgewater, Nova Scotia. One day this little guy flew in the door and at first appearance looked like a bee. Wrong! Upon closer inspection we noticed a very "pug" looking face, no stinger and two distinct tiny wings sticking up out of it's back other than it's primary wings. I wanted to take a macro of it while still alive, but before I knew it, it started laying tiny orange rice shaped eggs. I didn't want to disturb it but then it died by the next day after laying a huge pile of eggs. This is why I have it mounted on a pin. We've never seen anything like this before. Hope you can tell us what it is!  Thanks,  Carole
