female orb weaving spider

female orb weaving spider

5796  Can you please tell me what kind of spider this is. Found on a cement pad in Thunder Bay, Sept 13/2016 Sunny weather, Helen

This is a female orb weaving spider in the genus Araneus that has deposited her eggs and is approaching the end of her natural life. Both A. marmoreus and A. trifolium can have a similar appearance under this condition; I am inclined to believe that this more likely is A. trifolium.

Flea

Flea

5795   Found in our daughter’s bed after she woke up with bites!  Measures about 1-2mm – very small!  Thank you!  Susi.  Calgary.

This a flea that will feed on any warm blooded creature, especially humans.  To eliminate them in your home 1) Take your pets to a vet for treatment, 2) Vacuum, Vacuum, vacuum. 3) Have a pest professional treat your home with residual products that will kill the adults and insect growth regulators to eliminate the eggs and larva.  (IGR).

Sexton beetle

burying/sexton beetle Beetle with hitch-hikers

5794  Hi I’m wondering what kind of bug this is. It’s a beetle type bug with little red spiders/ticks all over it. It flew in my car window as I was driving. My name is Brad and I live in Bancroft Ontario Canada.

This is a burying/sexton beetle (Coleoptera: Silphidae) in the genus Nicrophorus. The little red critters are mites that are using the beetle as transportation (a phenomenon known as phoresy) to get to their next meal source – see http://tinyurl.com/gumcmra for an image.

Well fed bed bug

Well fed Toronto bed bug

5793  Last night I sent a picture of a bug I found in my bed. It was taken with my cell. I found a live version of this bug this morning on my carpet and have taken a better picture with my camera (I hope). I really hoping it isn’t a bedbug. Once again, I live in Toronto and this bug is easily squished and has a lot of blood in it. Thanks for your help.

This, unfortunately is a bed bug that has had a good blood meal.   The best control solution is to call an experienced pest professional.  In the mean time do not spray pesticides that could scatter them making it more difficult to find others.  See our web page for helpful information:

Reproductive winged ant

Reproductive winged ant

5790  Hi,   My name is Leslie and we live in Calgary.  We noticed hundreds of these flying insects (both large as in the picture and many very tiny ones as well) around a large window on our stair landing and then found hundreds more along the base of one wall in an unfinished part of our basement.  We sprayed the basement and it immediately killed them and then we vacuumed up the rest on the landing.  We haven’t seen a single one in the last  week so it seems we’ve eradicated them.  I would like to know if these little guys do any damage and if it’s likely they will come back.  Many thanks for your help!

This is a winged ant, likely a female ‘queen.’ Unfortunately, I cannot tell what kind it is from this image; the only ones to be concerned about from a damage standpoint are carpenter ants in the genus Camponotus. See http://tinyurl.com/zbfx3m8 elsewhere on this site for detailed information on these pests. Ed Saugstad, retired entomologist; Sinks Grove, WV.

cockroach nymphs

cockroach nymphs

5789  We are trying to identify the attached insects.  My location is Albuquerque, NM.  They are very small, between 4-5 mm (~3/16ths of an inch), end to end, not including antennae.  We are concerned these could be immature roaches, but we have lived here ten years and have never had them.  We have not seen any adult insects.  We are in a condo on the second floor, with one unit below part of our own.  The insects are showing up on the kitchen floor, either dead or dying.  We only spray outdoors, so we aren’t sure if these are coming in from the outside (deck, about 15 feet from the kitchen), or if they hatched inside.  If they hatched indoors, then we can’t explain what is killing them.  Also, we would expect to see a more signs, and greater numbers, not just two or three each day.  We have seen approximately eight total, but can’t identify where they are coming from. Thank you.  Any help in identifying the insects and recommendations to control is greatly appreciated. Kurt

These are very young cockroach nymphs, but I am uncertain as to exactly which species they might be. You might check with the owners/occupants of adjoining units to see if any had recently initiated any pest control measures. In the meantime, you might set out some ‘roach motels’ to see if you can get a better idea as to the extent of your infestation. Cockroaches essentially are nocturnal, so you might see only a few during the daytime even if a relatively heavy infestation is present. Ed Saugstad, retired entomologist; Sinks Grove, WV.

white-margined burrower bug nymph

white-margined burrower bug nymph

5788   Hi, this is Lili from Moncton New Brunswick. Found these bugs around outdoor plants in early September.  They are very small, with black head, red body with stripes. And they appear in groups. There are some little red things around them, not sure whether those are eggs or babies. Please help, thanks!  Lili

This appears to be a nymph of a white-margined burrower bug, Sehirus cinctus (Hemiptera/Heteroptera: Cydnidae). These are not pests that need any control; see http://tinyurl.com/zebkvpk for images and detailed information on its life history. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

Tussock moth caterpillar

Tussock moth caterpillar

5787   Hi.   This was found in Prince Edward Island (Sept 2016).  It is about 2” long +- and found on the grass by our propane tank. The 4 things on its back seemed to be soft and looked like the ends of paint brushes.  Any Idea of what type of caterpillar this is?  Thanks,  Derek

This is a caterpillar of a tussock moth (Lepidoptera: Erebidae; subfamily Lymantriinae) in the genus Orgyia; likely Orgyia leucostigma, the white-marked tussock moth. See http://tinyurl.com/3mjz472 for detailed information on its life history. Ed Saugstad, retired entomologist; Sinks Grove, WV.

crane fly

Crane fly

5786   My name is Nolen.  I live in Delta, BC and it’s late summer. What is this thing I killed?  Thanks,  Nolen

This is a crane fly.   The adults are a nuisance but considered harmless.  The species common in the pacific northwest are a serious problem because the larvae,  also known as leather jackets, feed on the roots of plants, mainly turf grass. Sometimes crane fly populations get high enough to cause damage to lawns.

termites

Reproductive termites

5785   From Al, BC coast, Canada.  Any idea what these are? quite a few around today in our house (September 3rd) never seen them before.  Many thanks

This is a pair (male pursuing female) of reproductive termites. They often form pairs like this after emerging from their colony and shedding their wings. After mating, the female will attempt to found a new colony. As most people are not keen on hosting these critters, locating a certified termite control service might be a good idea – see http://tinyurl.com/z6nhap8 elsewhere on this site for a starting point. Ed Saugstad, retired entomologist; Sinks Grove, WV.

broad-nose/short-snouted weevil

broad-nose/short-snouted weevil

5781  This bug was found inside our hotel room in Vernon BC. It is the third we have found in the bedroom.

Like Nos. 5779 and 5774, this is yet another broad-nose/short-snouted weevil (Coleoptera: Curculionidae; subfamily Entiminae). These weevils often enter buildings in search of shelter, but do no harm there. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

long tail black bug

Pelecinus polyturator

5780   I have been seeing this bug recently here in Saint John NB in my back yard. The bug is smaller then the photo makes it out to be. The body of the bug is about a cm and the tail would be about 4-5 inches. It also flies. Please let me know if you know what this bug is. Thank you!

This is Pelecinus polyturator  (Hymenoptera: Pelecinidae), it is parasitic on the larvae (grubs) of beetles in the family Scarabaeidae. See http://tinyurl.com/p9wnnt4 for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Cat-face orb weaver spider

Cat-face orb weaver

5778   It’s almost 2 inches big. It’s living between the windows (outside and inside) of townhouse in Edmonton. Photo taken mid August of this year. Please, please can you respond. Need to know if something to worry about, as there is a 1 year old baby as well 2 dogs. Thank you.  Dave H.

Nothing to worry about here – it’s a harmless orb weaver in the genus Araneus, possibly Araneus gemmoides, known as the cat-face orb weaver; see http://tinyurl.com/j9jjvy9 for an image. All orb weavers are harmless to humans. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Funnel weaver lair

Funnel Weaver spider lair

5777  Walking in the forest here in French River Ontario,  I came across a bunch of weird looking webs that I had never seen before.  I didn’t see any spider although i did look as close as I dared to.  lol  I have attached a few pictures of the tree with the webs.  I would greatly appreciate if you could identify these for me.  Thanks so much for your time!   Joanne. 

This appears to be the work of a spider in the family Agelenidae. Often called funnel weavers, these spiders lay in wait within their lair until a potential meal wanders onto the web, whereupon the spider rushes out to deal with it.

Wasp or fly larvae

5775  These larval sacks were protected in some fine insulating substance just like wool. Found them in a junction box on a wall outside.  (It even smelled like lambs wool.)  There were about ten of these brown, slightly crispy-shelled sacks.  Only one sack contained a set of 30 or so active larvae, the rest were nearly all milky, yellowish/white liquid. We’re in the Portland, Oregon, U.S. area. Really curious and unusual.  Can anyone help? Barrett and Susan.

This is another head-scratcher; I am unable to determine to my satisfaction whether these are wasp or fly larvae. If at all possible, can the contributor provide any image(s) of the sack-like structures before they were cut open? Ed Saugstad, retired entomologist; Sinks Grove, WV.

broad-nose/short-snouted weevil

5774     Hello,  We seem to finding more and more of these critters in our house near Calgary.  They started in one area in the basement and in an area in the garage but they are becoming more prevalent and found in other areas of the house.  They are only a couple of mm long and they are extremely slow moving.  When bothered they stop moving altogether and you could assume that they are dead.  They have 6 legs and a hard shell body.  The body appears to have a mottled, and slightly rough appearance.   What are they and how can we get rid of them?   Thanks,   Jeff

long-horned wood-boring beetle

5772   Hello.  I found this guy in a 5th wheel in Slave Lake AB.  He had hitched a ride from somewhere either there in the vicinity or in the Rocky Mountain House and Jasper areas. He was big for an insect, I thought, about an inch long….   I caught him in a plastic glass and put him outside. Any ideas?  I did look at your other pictures.  Lorie

This is a long-horned wood-boring beetle (Coleoptera: Cerambycidae). It resembles some species in the genus Monochamus (‘sawyers’); see http://tinyurl.com/zrsknym for an example. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Sink bug nymph

5771  Any idea what this bug is?  I found it on a leaf in my garden on August 6th, 2016, Mississauga, Ontario.  Regards,  Mike C

This is a nymph of a stink bug (Hemiptera/Heteroptera: Pentatomidae); possibly in the genus Podisus  – see http://tinyurl.com/gmmc6p4 for an example. Bugs in this genus are called soldier bugs; they are general predators on other small arthropods, including many garden pests. Ed Saugstad, retired entomologist; Sinks Grove, WV.

thread-waisted wasp

5770  Can you Please adv8ise what this is, photo taken in my sons backyard this evening , Aug 15, 2016, Cambridge, Ontario, Canada?  Thank You  Christine

Aphids

Aphids

5768  The attached photo was taken in the Boundary Waters of Minnesota in August, on the bark of a birch tree. It appears to be a tight cluster of fifty or sixty black 1/4″ six-legged insects(?), being “herded” (so it appears) by six or eight large black ants moving around the perimeter of the cluster. (You can see a couple of the ants on the periphery if you look carefully.)  Any help? Thank you.  Dick

These are aphids (Hemiptera/Sternorrhyncha: Aphididae), also known as plant lice, being tended by ants. The ants provide the aphids some protection against predators and in turn feed off the sugary secretions (‘honeydew’) of the aphids. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Bald faced hornets

Bald-faced hornets

5767  Hi my name is Diana and I live in Tecumseh Ontario and it is mid August. I have a Manitoba maple infestation of wasp like bugs that fly and sting. They are burrowing in the trunk of the tree.  There is no visible nest near them, yet they are swarming and burrowing into the trunks crevices from the ground up to  about 7 feet. We have a tree  that is approximately 20 feet away that has just recently died we’ve been told of Dutch elm disease, but I noticed these bugs in that tree as well.  There are bored holes throughout the trunk.  We thought the tree was in distress because of draught conditions here but it didn’t matter how much we watered it didn’t rebound.  Both trees looked very healthy in April /May.  The picture I am sending is of a medium sized bug… There are smaller ones and there is also a much larger one that I have seen where the body is almost 2 inches longer. 

These are bald-faced hornets, Dolichovespula maculata (Hymenoptera: Vespidae). They do not bore in trees, but may thoroughly investigate any crevices/cavities for other arthropods to prey upon. At this time of year, they still are primarily carnivorous, seeking out protein to feed their young. See http://tinyurl.com/htdelhs for more detailed information.

Mud dauber wasp

Mud dauber wasp

5765  Can you tell me what this is and is it dangerous?

This is a thread-wasted wasp (Hymenoptera: Sphecidae), it appears to be Sceliphron caementarium , known as the black-and-yellow mud dauber. They are  of danger only to the spiders that they capture, sting, and paralyze as provisions for their larvae.

Stink bug nymph

Stink bug nymph

5764   Good evening,  I came upon your website when I was trying to identify an insect I found outside in my tomato garden. I scanned through some pictures on your website but I didn’t see my exact bug. I’ve attached 2 photos of it having some lunch. I took these today, August 7th in Nova Scotia. It’s been fairly warm and dry here lately, if that matters. I have 3 raised garden beds inside a chain link dog kennel enclosure (to keep deer from eating my tomatoes) Anyhow, that’s where this sucker was at, on one of the posts.  Thanks in advance for any help you may be able to provide.  Kelly

This is a nymph of a stink bug (Hemiptera/Heteroptera: Pentatomidae) in the genus Podisus.
