Harmless ground spider

5689  Hi, my name is Desiree. I found this spider in a house I work at. The area/location is Qualicum Bay, Central Vancouver Island, BC, Canada. Month is early June.  It was about the size of a dime. Maybe slightly smaller. And was quite quick. I have never seen one quite like this out here and am very curious as to what it is. Thanks in advance. 

This is a ground spider (family Gnaphosidae) in the genus Sergiolus; either S. columbianus or S. montanus. The markings of these species are very similar, and a positive i.d. often depends on microscopic examination of their genitalia. These spiders are harmless to humans.   Ed Saugstad, retired entomologist; Sinks Grove, WV.

whitespotted sawyer beetle

5688  Hi, this bit me! Should I be concerned?  Please identify. I’m in Port Coquitlam BC and it was in my kitchen. (Door is open as very hot).

Thanks, Sandy

5688  This is a long-horned wood-boring beetle (Coleoptera: Cerambycidae) in the genus Monochamus; likely M. scutellatus, known as the whitespotted sawyer, As a wood-borer, it has very strong jaws, but there is no danger from its bite – see http://tinyurl.com/hxozfrufor more detailed information on this species. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Earwig

5687  I found this creature in a glue trap  along with a spider and an ant.  Care to guess what it might be?  Many Thanks,  Ross

This is an earwig (order Dermaptera). Earwigs are very common nuisance pests that usually do little if any actual harm; occasionally, they may cause damage to very tender vegetation. Ed Saugstad, retired entomologist; Sinks Grove, WV.

bed bug

Dead bed bug + ?

5686.   hello my name is Line these are the pest that are in my apartment. I live in Niagara falls Ontario and the weather is just starting to get warm. The pest are very small not sure the size as some are a little bigger then others , also have wings.They do bite as I am covered in bite marks and have a very itchy and burning feeling. Once bitten they are small and then start to swell up if scratch causing irritation to the skin. 

You may have two different pests. The image you provided looks like the remains of a dead bed bug, which would explain the itchy bites. However, these insects do not have wings. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Lawn Shrimp

5685  Hello,  My name is Dziepy.  I found about 50 of these bugs underneath my leather couch while sweeping my wooden floor living room.  The couch sits directly in front of a glass sliding door that we do not open. The skin has a shiny sheen to it. Only 5 or so bugs have no sheen but were dark brown and smaller in size.  3 of the small dark brown bugs were still alive, moving and twitching. I live in Arlington, Texas. It has been raining on and off for the past 2 weeks with temperature in the 60s-70s when it rains and upper 80s and muggy when not raining.  Thank you for your help in identifying these bugs.

These are terrestrial amphipods (a type of crustacean) commonly known as lawn shrimp. They are harmless nuisance pests and there is no need for control measures.  See http://tinyurl.com/o3d2f34 for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Scarab beetle

5684   Hi my name is Marlinta and I live in Montreal, Canada. I have found a couple of these insects walking around my garden lately.  I’m pretty sure the last one was in the soil inside a flower pot.  I have had Japanese beetles in the past.  These guys are huge…about 1/2 inch yuck!!!  Any help would be greatly appreciated!!!

This is a scarab beetle (Coleoptera: Scarabaeidae), likely in the subfamily Melolonthinae. Several species in this subfamily can be serious lawn/garden pests. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Beetle Larva

5683   Found this bug walking very quickly through the shade of our driveway (Nova Scotia), it stayed out of the light, and looks similar to firefly larvae, but it has two little prongs on the back, kind of like an earwig, and didn’t use it’s tail to move, just it’s 6 little legs. it was a bit over an inch long.

This is a beetle larva, but definitely not that of a firefly or any other closely related family. I will try to come up with a more specific identification when I have time to do a bit of research. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Dragonfly nymph

5682   Hi,    My name is Claude. These photos taken on May 26, 2016 at 3:00 in the afternoon, close to a lake, in Val des Monts, Quebec, Canada.

This is an immature stage (nymph/naiad) of a dragonfly. It might be in the family Micromiidae (cruiser dragonflies) – see http://tinyurl.com/zpwnavo for an example. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Ground Squirrel

5681  Hi, I took these pictures today, May 22nd in Beaver Bank, Nova Scotia. Can you tell us what it is? Thanks, Myles 

This looks like a ground squirrel but I can’t be sure which species.   Larry Cross. Webmanager
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
This does belong to the same family as ground squirrels, but it is a woodchuck (Marmota monax), also known as a groundhog or whistlepig. These can be serious garden pests. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

Male Carpenter ants

5680   Sandy from Victoria BC.  These guys started appearing on the inside of one basement window at a rate of about 4 per hour, but I can’t see where they’re coming in.  There’s no sign of them outside, so not sure if they’re migrating in or hatching indoors somewhere. It started on May 20 after a long warm spell followed by a few days of cooler cloudy conditions. No rain at all.   Thanks in advance!  Sandy

These are male ants, possibly carpenter ants. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Bumble Bee

5678   Hi. I am Adina, Montreal . Found this guy on my basement floor. The  another one a few hours later. No idea what it is. Could you help identify? Thank you

This is a bumble bee (Hymenoptera: Apidae; Bombus sp.). These are valuable pollinators, so when they blunder indoors, you should try to escort them outside. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Weaver?

5677  Hi there I found this spider under a rock by the Brazeu river near Drayton Valley Alberta. Couldn’t find him in any of my books.

This one is seriously puzzling to me; I want to say that it is a hackle-mesh weaver (family Amaurobiidae), but I am not at all confident of that. A close-up of the eye pattern would be a great help, but you likely do not have that. I may try to some more digging on this one later. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Flower Beetle

5676 Hello, I live in the Ottawa area and a few of these tiny bugs have been in my bathroom this week. The photo doesn’t show but it’s quite tiny and appears to have wings that fold over the back end. If you have an idea as to what it might be I would really appreciate hearing from you.  Sincerely,  Christine

This is a soft-winged flower beetle (Coleoptera: Melyridae); it looks like Anthocomus equestris – see http://tinyurl.com/gtxgprz for an image. They appear to be pollen feeders. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Bed bug on leg

5675  Hi, I found this crawling on my leg today while I was at home, not sure where it came from. Is this a bed bug? It is very small so that’s the best photo that I could take. I live in Vancouver. Thanks, Polina

Unfortunately, this is a bed bug, and it appears replete with a blood meal (possibly your blood). See http://tinyurl.com/hwz5tea elsewhere on this site for control information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Broad-nosed/short-snout weevil

5674  Hi,  I’ve noticed these little guys appearing in several places in my home recently with the warm weather. Wondering if you can id it. I have looked through the images but didn’t see one that matched.  Size – about 7mm,  Month – May,  Weather – dry and warm.  Thank you very much for your help.   Neil – Calgary Alberta Canada

This is a weevil (Coleoptera: Curculionidae) in the subfamily Entiminae. Known as broad-nosed/short-snouted weevils, they frequently enter buildings in search of shelter, but do no harm there. Their larvae feed primarily on plant roots, and some can be serious pests. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

Click Beetle

5673  What is this beetle? Sharon.   Outside.  Langford, BC

This is a click beetle (Coleoptera: Elateridae). I cannot be certain from this image, but it might be Selatosomus suckleyi – see http://tinyurl.com/jdrktbc for an image. Very little appears to be known about the life history of this species. Ed Saugstad, retired entomologist; Sinks Grove, WV.

long-horned wood-boring beetle

5672 Hi there. I assume this is some sort of “long-horned wood-boring beetle” but would love more specifics. This guy and a number of his brethren chewed their way out of hardwood (mulberry) we had brought in for the fire from our woodpile. They have emerged over the past few days (early May).  Body just around an inch long. In Scarborough, ON. The holes are almost squared more than round.  Thanks in advance!  Deborah

This is a long-horned wood-boring beetle (Coleoptera: Cerambycidae); it does not appear to be any of the species that might infest anything in your home. Ed Saugstad, retired entomologist; Sinks Grove, WV.

House Centipede

5671  Hi, my name is Jane, I am in Ottawa, Ontario I found this guy n my kitchen, it’s spring with warm dry weather. I think it came in from the yard on a blanket. It looks similar to the house centipede but not sure. It’s about an inch long with very long striped antennae-type “legs”. Thoughts?

This is indeed a house centipede (Scutigera coleoptrata); see http://tinyurl.com/mn7mzf for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

Stonefly

5670   This guy I found on my girlfriends back after we went outside for a smoke at 4 am in Edmonton Alberta. Let’s just say he won’t be bothering us no more but would like to know if they are common or not here. May13 2016 this was taken. Thanks for your help.

This is a stonefly (order Plecoptera).Their immature stages (nymphs/naiads) are aquatic, and are an important source of food for many fishes. The adults live just long enough to find mates and lay eggs; some never feed at all as adults, but simply live off fat stored as immatures. See http://tinyurl.com/h84682m for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Booklouse

5669   Hi,  I found this bug in my one year old condo in Toronto.  They are very tiny, about 1-2 mm long.  They mainly locate in the bathroom floor, but also found in the bedroom drywall as well.  I also located them in the main entrance dry wall. The humidity of my home is around 30%.  I used Raid Max (indoor) spray around the house but the problem still persist.  I also used bleach to clean around the bathroom couple of times as well.  I understand it mainly for identify this bug.  However, if you have any suggestion how to get rid of it, I will be very appreciated about it. Best,  Kelly

This is a booklouse (Psocodea: Liposcelidae). These basically are nuisance pests that feed primarily on mould spores found on damp/spoiled organic materials. They do no real damage, and chemical control almost never is necessary. Besides lowering indoor humidity levels (which you already have done), check for and eliminate any unnecessary sources of moisture. See http://tinyurl.com/hqm566h for more detailed information.

Noisy Bug: metallic wood boring beetle

5668  This beetle picture is being sent to you for a friend of mine.   Can anyone tell me what kind of bug this? It is noisy when it flies and I believe that it bites rather like a horse fly or deer fly. That is a 1X4 that it is on in this picture, just for size reference.  The picture was taken in Armstrong, BC.  Thank you,   Lyndon

This is a metallic wood-boring beetle (Coleoptera: Buprestidae); it looks like something in the genus Chalcophora (see http://tinyurl.com/z4t28nf for an example). Ed Saugstad, retired entomologist; Sinks Grove, WV.

Assassin bug nymph

5667  Hi, I found this insect on my daughter’s neck today. When I got it off of her and was taking a picture, it seemed to be aggressive like it was making itself look big. I’m in Abbotsford, BC. It has been in the high 20’s to low 30’s here. Can you please help me identify it? I currently have it in a bottle with a branch and leaves in case it is a pest.

This appears to be a nymph of an assassin bug (Hemiptera/Heteroptera: Reduviidae). They are general predators on other arthropods, and can give one a painful stab with their beak if mishandled, but they are not at all dangerous to humans. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

 

Fairy Moths

5666  We live in a rural area in Victoria B.C. and have notices hundreds of these flying bugs outside. We have never seen these here before. I hope you can help. Thank you Norma

This might be a fairy moth (Lepidoptera: Adelidae); see http://tinyurl.com/hgycfhl for an example. Some species in this family have very long antennae and are active during the daytime. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

Mushrooms?

5665   I found these eggs attached to the inside of one of my deck boards.  Photo was taken May 2016 from Windsor, ON Canada. Should I be worried?
Thanks for your time.   Michelle

These look like small puff ball mushrooms. We are not experts on mushrooms so you may want to check the structural integrity of the deck.   Fungus grows on wet decaying wood.

 

Death-Watch beetle

5664 Found about 40 of these bugs one night in my basement. They are very small and these photos are the best I could take.  They do fly around. Live in Guelph Ontario. and it was April 30 when observed. Please help identify so I can get rid of them. Thanks,  Trevor

This looks like a male death-watch beetle, Ptilinus ruficornis (Coleoptera: Ptinidae); see http://tinyurl.com/pavqd3q  for an image. Their larvae bore in dead wood of broad-leaved trees such as beech, maple, oak, and sycamore, but they also have been reported as pests of woodwork in homes. You may wish to consult a professional pest controller for advice. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Flea

5663  Hello,  Attached find a photo of a pest we found in our bed the night after my daughter got three nasty bites. They became swollen red bumps by the next morning, and are quite itchy, but not painful. No other symptoms. For scale, the bug is about 2-3mm long.  I suspect our cat, who is an outdoor cat who has picked up fleas before. However, this doesn’t look quite like a flea, so I wanted to be sure..  Please help! Whatever it is, any advice as to treatment word be most appreciated.  Thanks,    -Eyal

This does look like a flea, but because this is a dorsal (top side) view, it appears very narrow, as fleas are quite flat from side to side. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

Modoc carpenter ants.

5661 &5662  Hi,  There seems to be an uprising of these large ants in the last couple days, in multiple locations around Wakaw Saskatchewan.  Just wondering what they are and if they need to be exterminated? Thanks in advance! Jaimie. 

These are female reproductive carpenter ants, probably Modoc species. The ant on the right has been fertilized and has removed her wings. (See the scars on her thorax)  She will be seeking wet wood to burrow into and start a new nest. She will lay about 70,000 eggs over the next 15 years.   Read more about carpenter ants.

 

Checkered beetle or flower beetle

5659  Hi there! Wondering if anyone knows if this bug could be the pest that is biting my daughter multiple times and leaving horrible bites!? (100% she is not being bitten by bed bugs).  We are in Ontario. Thanks so much! Kristin

This insect would not be responsible for any bites, it looks like either a checkered beetle (Coleoptera: Cleridae) – see http://tinyurl.com/zahbs2d for an example or a soft-winged flower beetle (Coleoptera: Melyridae) – see http://tinyurl.com/blmwg7d for an example. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

Scarlet Malachite beetle

5658   I wonder if you could help me identify some critters that have been climbing my living room windows in the last few days. They have a red shell, with a dark stripe down the center of the back, covering the wings. They are approximately 1/2 inch long.   Thank you very much.  Reg B.  Edmonton

This appears to be a scarlet malachite beetle, Malachius aeneus (Coleoptera: Melyridae); see http://tinyurl.com/zqh9yee for an image. The larvae of these beetles are predaceous on other small arthropods. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Leaf Beetle

5657  Hi my name is Matthias.  Last few weeks a lot of these guys have popped up in my house. I live in Brampton Ontario Canada. They’re mainly on my ceiling and high up on my walls, they fly and are 2-4mm when we get a closer look they tuck their feet in and dont move.

This is a leaf beetle (Coleoptera: Chrysomelidae) in the subfamily Bruchinae. Known as pea or bean weevils, their larvae develop in dry seeds, primarily legumes such as peas and beans, so if you have any such in storage, you should check them for signs of infestation. See http://tinyurl.com/jdjg8a8 for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

Trapdoor spider

5656   Hi, I dug up a fern in my mother’s yard and came across this spider.. With the whole body it was about the size of a toonie.. My mother lives in Langford BC. ( Vancouver Island ). I have never seen anything like this and am very curious if you could tell me which kind of spider this was.. I did not keep it and let it go.. Thanks, Christine

This looks like a female Antrodiaetus pacificus, a folding-door trapdoor spider in the family Antrodiaetidae; see http://tinyurl.com/lp7j62z for an image and nos. 5638 and 5640 for other examples. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Larder Beetle

5653 Hi,  I’m from Ottawa, ON. I keep finding these in our house. Maybe a beetle? They’re pretty small (no bigger then 5mm?), black body with brown it.  Your assistance is appreciated,  Marc.

This is a larder beetle, Dermestes lardarius (Coleoptera: Dermestidae), a cosmopolitan household pest. See http://tinyurl.com/go89o66 for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Leaf Beetle

5652   This is an odd bug that I constantly find on the screen door and sliding door of my cabin on the water, in Osoyoos, BC. Canada’s only desert. I’m not sure where they come from, but they re-appear nearly as fast as I can kill or get rid of them, at all times of day, but there’s never more than 2-3 at a time, even if I leave them alone. There quite small, as you can see it sitting on the screen door mesh in the background. I’m not sure if they fly or not. Sometimes when I brush them or blow them off they fall to the ground. Other times they flutter to the ground, but don’t fly away. They don’t do anything that I know of, I just don’t enjoy them spending there time here.

This is a leaf beetle (Coleoptera: Chrysomelidae); it looks like an elm leaf beetle, Xanthogaleruca luteola, see http://tinyurl.com/z9zbzd6 for more information. Ed Saugstad, retired entomologist; Sinks Grove, WV.
