Black vine weevil

Black vine weevil

I am from Toronto, I found this thing walking around my bedroom. It is about one cm. 

6149  This is a short-snouted/broad-nosed weevil (Coleoptera: Curculionidae; subfamily Entiminae), likely a black vine weevil (Otiorhynchus sulcatus).  Adults will occasionally invade homes but they cause no harm there.

caterpillar of a swallowtail butterfly

caterpillar of a swallowtail butterfly

I came home from work today to find this little guy crawling on the side of our house! Any idea what it is?  Thanks Dave

This is a caterpillar of a swallowtail butterfly (Lepidoptera: Paplionidae) in the genus Papilio; see https://tinyurl.com/y7c8pns8 for an example. These caterpillars often change from green to brown as they get ready to pupate.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

rodent bot fly

rodent bot fly

6148    Found in interior BC near Nelson in August.  Approximately 1.25 inches long (large).  Unable to identify.  Lauren 

This is a rodent bot fly (Diptera: Oestridae; Cuterebra sp.). Their larvae develop under the skin of several species of rodents; the adult flies lack functional mouthparts and are harmless.

golden buprestid beetle

golden buprestid beetle

6147   I’m from Parksville, B.C. I found this dead bug burrowed in my carport wood beam also when removing a rotted piece from a beam I found a larvae. Here I thought termites were my biggest problem. I had already squirted some termidor poison in all the visible holes, I also removed a sunflower seed they must have used as a plug. What are my options?

This is Buprestis aurulenta, a metallic wood-boring beetle (Coleoptera: Buprestidae) sometimes called the golden buprestid or jewel beetle. This species can spend a remarkably long time in its larval stages; see https://tinyurl.com/ycs5h2sj for detailed information. At this point, there is no useful control option; see https://tinyurl.com/yakc6r4x for details.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

larder beetle, Dermestes lardarius

larder beetle, Dermestes lardarius

6146   This is some kind of beetle, but I’ve never seen it before. Found indoors in Saskatchewan today (Oct. 3). The photo is taken on the dining table, so please excuse the grainy background.  Lisa 

This is a larder beetle, Dermestes lardarius (Coleoptera: Dermestidae), a cosmopolitan pantry pest. See https://tinyurl.com/nw92wz  for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

brown marmorated stink bug

6145  We are finding the bug on our window. I have pleaded blinds in the front window and they are crawling I’m the pleats. They are half a inch or three quarters of a inch they have wings and are brown with a light stomach. 

This is a brown marmorated stink bug, Halyomorpha halys (Hemiptera/Heteroptera: Pentatomidae), an introduced species that has become a pest in much of North America. See https://tinyurl.com/nkexo3 for more detailed information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

6143  What is it, I found it hiding on my porch.

This is a long-horned wood-boring beetle (Coleoptera: Cerambycidae) in the subfamily Prioninae, it looks like Tragosoma depsarium; see http://tinyurl.com/y7g53rba for an image. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

Slug, snail, chrysalis?

6142   I didn’t see anything else like this odd little thing on your site. It was found at Victoria Beach, Manitoba, in August (summer), outdoors on a nice day – 25-ish degrees Celsius. Thanks for looking at it – your site is great.  Ida

I cannot tell for certain what this is – if it was moving and very soft in texture, it would be a slug, a shelless mollusk related to snails. If it was hard to the touch and immobile, it might be a chrysalis of a small butterfly. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Japanese beetle

Japanese beetle

6139   We have found two of these bugs on our deck this summer. We live 60 miles west of Toronto.  I do a lot of gardening and suspect they like it.  The white spots along he lower body were interesting enough for me to ask what bug is this.  Thank you,  Alex

This is a Japanese beetle, Popillia japonica (Coleoptera: Scarabaeidae), an introduced species that has become a serious pest in much of North America. See http://tinyurl.com/hzjj3my for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

dog mite

Dog mite

6138  Hi! I’m hoping someone can help me identify this bug. I found a few on my bedding today, my dogs also sleep on the bed. They were tiny… not even a millimetre, the few I saw were reddish brown in colour. The attached is under 4x magnification.  thank you,  Juliana.

Your photo is a bit dark for identification but is does look like a mite. Definitely not a bed bug.

metallic wood-boring beetle

metallic wood-boring beetle

6136   Hi   I found this shiny brown bug inside, on the cold tile floor. The location is lakeside, at Seeleys Bay, about 30 minutes north of Kingston, Ontario.  The bug is about 1cm in length (about the size of a dime).  I looked through beetle (and cockroach) references on- line but didn’t see any creatures with this kind of hind end. Would be so pleased to learn what it is.   Thank-you, Jennifer. 

This is a metallic wood-boring beetle (Coleoptera: Buprestidae); it looks like a member of the genus Dicera – see http://tinyurl.com/yck2f6ox for an example and http://tinyurl.com/yb2k33qe for additional information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

Masked Hunter

6134   Hi.  This bug was just inside my house in Nova Scotia. Is this a form of tick?

This is a masked Hunter. Both adults and nymphs are predators that feed on other insects including flies, carpet beetles, mealworms and bed bugs. The adult bug is dark brown or black and about 3/4 of inch long. The nymphs or immatures are covered with microscopic hairs which catch and hold dust, lint, and other small particles of debris.

Carpenter ant nest damage

6133   Hi, there,  I saw this under my deck. Did not see the ant, but I am wondering if it sign of white ant?  Thanks a lot. I live in Burnaby, B.C.  Jerry

The holes and course wood fibre (frass) indicate typical damage caused by carpenter ants. See this web page for more information: http://pestcontrolcanada.com/ants/carpenter-ants

long-horned wood-boring beetle

long-horned wood-boring beetle

6132 Hi.  We found this beetle by the garage in July in Grand Forks BC. I couldn’t find any photos to match on the website.  Can you identify it?  Thanks,  Lennette. 

This is a long-horned wood-boring beetle (Coleoptera: Cerambycidae); it looks like Prionus californicus – see https://tinyurl.com/2ue3qel for an image and detailed information on its life history.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

flat-backed millipede

flat-backed millipede

6131  Hello! My name is Nikki.  I found this guy at work in the gorge today, at the base of the Niagara Falls. Ontario, Canada

This is a flat-backed millipede (family Polydesmida) in the family Xystodesmidae; it looks like Sigmoria trimaculata – see https://tinyurl.com/yct6dqg9 for an image. These are harmless detrivores, but have an interesting defensive mechanism. When disturbed (as in being handled roughly) some species give off a chemical compound that includes cyanide (not enough to be harmful to a human. If you sniff one carefully, you might detect a faint odor of almonds. Ed Saugstad, retired entomologist; Sinks Grove, WV. 

reproductive termite

reproductive termite

6130    On September 8, 2017 we found aprox. 50 bugs in our home. We have never had a bug problem in the past. We spent the night vacuuming and were hoping that they were gone, unfortunately two days later they are back.   Size :  aprox 2 mm,  month: September,  after a hot dry summer, we first found them after the first rain fall.  These photos were taken on Sept 10 after another short rain fall. We are a one story home with a cement/ dirt crawl space. They are in all of our rooms. We are hoping to find out whether this needs to be taken care professionally and what they are. We are in the regional district of Nanaimo BC, in the village of Cedar. Thank you.  Laura and Gordon

This is a reproductive termite that has shed its wings; it appears to be a Reticulitermes sp. As termites in this genus can be quite destructive, you should consider contacting a reputable termite management company for a thorough inspection of your premises.

flea beetles

flea beetles

6128  Hi there.  Would you mind please helping me identify this beetle. Found on a grapevine in Southern Okanagan,  Duncan

These appear to be flea beetles, possibly grape flea beetles, Altica chalybea (Coleoptera: Chrysomelidae); see https://tinyurl.com/y9sfpcuo for an image. Foliage feeding such as shown in your image seldom causes any serious harm to the plants, but overwintering adults feeding on developing buds in the spring can have an impact.

black burying beetle

black burying beetle

6127  Dear Sir/ Madam, Kindly help me identify these insects. Photo was taken in Mission, British Columbia, Canada on the last week of August, 2017.  I am not sure if those insects at the back of the beetle are its babies or some kind of “Tick’? Thanks very much in advance! Martin

This appears to be a black burying beetle, Nicrophorus nigrita (Coleoptera: Silphidae); see https://tinyurl.com/y8r24ma6 for an image. The smaller critters on its back are mites, likely Poecilochirus necrophori. These mites are getting a free ride (phoresy) to their next meal (they appear to feed both on carrion and on the eggs/small maggots of carrion-feeding flies). See https://tinyurl.com/y7tjr32o for details on the beetle-mite relationship. Ed Saugstad, retired entomologist; Sinks Grove, WV.

carpet beetles

carpet beetles

6126  My name is Amanda. I am located in downtown Toronto & I have just found an accumulation of these dead bugs in my window sill. They are approx. 2mm in length. There appears to be 2 different kinds – one with a bronze coloured body, the other with a speckled grey body. They appear to have wings.The apartment has been closed up while we were away on summer vacation and these were located between the blind and the window.

These are carpet beetles (Coleoptera: Dermestidae); the brownish elongate ones appear to be in the genus Attagenus (black carpet beetles and allies) and the round gray one appears to be in the genus Anthrenus (varied carpet beetle and allies).

scarab beetle

scarab beetle

6123 Hi There –  I live in Winnipeg, Manitoba & found this 2 inch × 1.6 inch huge beetle on the sidewalk outside of my apartment a few days ago. It’s been quite humid all week & rather hot. Never seen a beetle this large ever, let alone in the Canadian prairies before. Where might it have originated from? How old might it be or live to be?  Thank you so much! All the Best, Tann 

Like nos. 6109 and 6105, this is a scarab beetle (Coleoptera: Scarabaeidae) in the genus Osmoderma; see https://tinyurl.com/y9bs48g3 for an example. Their known range extends well up into Canada. Ed Saugstad, retired entomologist; Sinks Grove, WV.

rove beetle

rove beetle

6120   Hello,  This was discovered on the hood of a car downtown Ottawa mid-August 2017.  All that I can gather from Web research is that it may belong to a wood boring insect, but nothing is matching any descriptions for Ontario.  It is close to an inch long. I’d appreciate any extra information if you may have it. Thanks,  Christa

This is not a wood-boring insect of any kind, it is a rove beetle (Coleoptera: Staphylinidae), which are general predators on other small arthropods. Your specimen has its flight wings exposed; these usually are tightly folded under short wing covers (elytra) – see https://tinyurl.com/y7rudl85 for a more typical image. Ed Saugstad, retired entomologist; Sinks Grove, WV.

flea beetle

flea beetle

6119   Hi there, Jordan from Winnipeg here. There have been a lot of these insects popping up over the last couple of days (mid August). They are tiny black beetle like insects with yellow stripes on the sides that will land on anything including the side of the house, furniture and people. They fly away very quickly once disturbed. Slightly smaller than a poppy seed. Not bothersome, but they are prevalent and noticeable, especially to those with leg hair! Thanks. 

This is a flea beetle (Coleoptera: Chrysomelidae; subfamily Galerucinae) in the genus Phyllotreta – see https://tinyurl.com/y9slbz7h for an image. Some species in this genus can be pests on plants that are members of the cabbage family. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Mormon cricket

Mormon cricket

6118   Hello! I found this guy outside of Pilot Butte, Saskatchewan in the middle of August on a cool cloudy day around 10AM. It was about 1-1/4″ long from the end of the stinger to it’s head. Would love to know what it is!! Thanks!

This appears to be a female Mormon cricket, Anabrus simplex (Orthoptera: Tettigoniidae) – see https://tinyurl.com/ydh24fee for an image. The ‘stinger’ is its ovipositor, used to insert its eggs into soil. Although called a cricket, this insect actually belongs to a group known as shield-backed katydids; see https://tinyurl.com/ycwdxf8v for more detailed information.

6117  Good day, this was found in Medicine Hat, Alberta and we are just curious if we should be concerned. About half an inch long, it was found in my husbands locker at work where he stores his shoes/boots. Thanks so much for any info. Darrah

This is a solpugid; an arachnid in the order Solifugae, related to spiders and scorpions. These go by a wide variety of common names, including camel spider, sun spider, and wind scorpion; they lack venom, but large specimens can deliver a painful bite if mishandled.
