caterpillars of Abbott’s sphinx moth

caterpillars of Abbott’s sphinx moth

6070  Hi.  Ann in Winnipeg it’s July 11.2017.   Found these two guys in my yard?    What are they??

These are caterpillars of Abbott’s sphinx moth, Sphecodina abbottii (Lepidoptera: Sphingidae); see https://tinyurl.com/y9glgn73 for more detailed information. The one on the left had been parasitized by a wasp in the family Braconidae; after the wasp larvae finish growing, they chew through the caterpillar’s skin to spin their cocoons. Adult wasps eventually will emerge from these to seek out more caterpillars. Ed Saugstad, retired entomologist; Sinks Grove, WV.

June Bug

June Bugs

6069  Hi there, my name is Mark from Halifax, Nova Scotia.  While I am very familiar with June Bugs, these flying beetles are a mystery.  They resemble a mini June bug (about half the size) and usually start swarming at dusk in humid temps. I live in a 6th story penthouse apartment, and it is July, and they have no problem coming up to swarm. Thanks! Mark

June Beetles are Scarab beetles which appear in large numbers at this time of year. There are two general types-big and small which seem to suddenly appear in spring and then vanish about a month later. Both are from really big groups which consist of a couple hundred species apiece. The small ones are from the genus Cyclocephala, also known as masked chafers. As larvae they’re lawn pests known as ‘white grubs’ and commonly feed on grass roots and thatch near the surface of the soil. They take two years to grow from egg to adult.

The big ones are from the genus Phyllophaga, and are sometimes called May Beetles depending on where you are. They’re about twice the size of the smaller Cyclocephala. They take about 3-4 years to grow to adults. Like the masked chafers, these June Beetles feed on roots of plants and can cause damage to a wide variety of plants.

Sow bugs

Pesticide abuse

6068  Can someone please help me and tell me what these are, and if I have a big problem… I just moved into a new place in Calgary Alberta. My name’s Meagan. These bugs are dead, but maybe because I sprayed the WHOLE place with raid, including that spot the picture is at… They seem to be stuck in the glue? I’ve seen many of them.. and the centipede looking thing on the right hand side.. I’ve seen a couple of those alive around the house… No one has lived here in awhile I guess.. the guy said that the house is gonna get torn down if no one rents it… There’s many cracks everywhere.. I’ve used like 7 cans of raid (spider blaster and reg raid) in the last week I’ve been here.. the sightings of bugs have kinda stopped.. but once I opened up the side base boards and seen that (the picture above..) I couldn’t believe it. Is this bad? Please help.

These are sow bugs that probably died because they can only survive in a very damp environment. Spraying pesticides is not recommended to eliminate sow bugs.  Spraying 7 cans of raid is irresponsible and could cause health problems to the occupants in the home. You obviously did not follow the label directions and that is against the law.  Read our suggestions to control sow bugs.  

clear-winged sphinx moth

clear-winged sphinx moth

6067  Hi.   My friend took this in Gander, NL in his garden.

This is a clear-winged sphinx moth in the genus Hemaris, likely H. thysbe, a very widespread species known as the hummingbird clearwing. See https://tinyurl.com/3ufbql4 for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Boxelder bug nymphs

Boxelder bug nymphs

6066  Could you tell me what this is please. They are on the leaves and there are hundreds of them.  I live in Woodstock Ontario and this was taken this afternoon. Thanks. Linda

These are nymphs of a boxelder bug, likely eastern boxelder bugs, Boisea trivittata; (Hemiptera/Heteroptera: Rhopalidae). These can be nuisance pests when they occur in large numbers, but they seldom cause any real damage. See https://tinyurl.com/nrlf5m for more detailed information.

Cockroach (Ectobius)

Cockroach

6065   Photo of a beetle I saw outside my house. At first I thought it was a German cockroach but it didn’t have the dorsal stripe I expected to see. Located north of Toronto, Ontario, Canada.  Thanks!   Jamie

This is a cockroach in the genus Ectobius, a relatively recent introduction to North America from the Mediterranean region. See https://tinyurl.com/y8mvu3kd for an image and https://tinyurl.com/yd2fpjab for more detailed information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

short-snouted/broad-nosed weevil

Short-snouted/broad-nosed weevil

6064    Hi , we keep finding these bugs in our cabin  we just renovated in the last 2 years and all our in side walls are pine boards , they seem to be in the bathroom mostly but have found them elsewhere in the cabin as I have sticky traps set out also . we are at Pigeon  Lake Alberta , Canada,  they have just shown up in the last 2 weeks  so not sure what they are , thanks Kevin   

This is a short-snouted/broad-nosed weevil (Coleoptera: Curculionidae; subfamily Entiminae), but the image is not clear enough for a more specific identification. The adults often enter buildings where they basically are nuisance pests that cause no serious harm, but their larvae can be serious pests – see http://tinyurl.com/monvaej for detailed information.

male eastern dobsonfly

male eastern dobsonfly

6063    Please identify.  Emma in Tweed, Ontario

This is a male eastern dobsonfly, Corydalus cornutus (Megaloptera: Corydalidae). Their impressive-looking jaws actually are quite harmless; at most, they can deliver a mild pinch. The much shorter and stouter jaws of the female, on the other hand, can draw blood with their bite. The larvae of dobsonflies are aquatic; known as hellgrammites, they also have very strong jaws and should be handled carefully. See https://tinyurl.com/256o98e for more detailed information.

Dermestid beetle larvae

Dermestid beetle larvae

6062  Hello! We live in Waterloo, Ontario, Canada. My wife recently woke up with about 12 bug bites, solid red, itchy splotches that are swollen. Bites appear in two groups of three on her right arm near the elbow and near the armpit. Single bites appear on the inner thigh, knee, and hip of her left leg. They are very itchy. (She reacts very strongly to bug bites, such as mosquitoes.) We immediately thought of bed bugs. However, when we stripped the sheets we found this creature crawling on the mattress. We would appreciate it if you could identify it and say if it might be responsible for the bites. We will continue our hunt for bed bugs in the mean time. Thanks!!

This is a Dermestid beetle larvae.  Dermestid larvae feed in dark, quiet areas on a number of stored food items as well as animal products (wool, silk, leather, fur, hairbrushes with natural bristles, and feathers) that are of value to people.  This was not the cause of your bites.   Your description of the bites sounds like you could have a bed bug problem.  You may be wise to have a professional do an inspection for bed bugs.  They can be difficult to find.

Plant bug

Plant bug

6061   Hi my name is Nadine from Edmonton, AB. This bug I found after I came inside from out on the front area of my building. I sat down on my couch and put my feet up to feel a lil movement on my leg. I freaked to see this guy and grabbed him (he lost a leg in this process) to put him in a container. I’m a lil sensitive after going through bed bug cleaning and spraying for 3 months. A lil paranoid maybe.. It’s a warm evening where the sun was setting and a slight cool breeze. I’m not sure if this guy hitched a ride from outside or my house is hiding more friends??? What is he?

This is a plant bug in the family Miridae; just an accidental intruder that you need not worry about. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

too small

Too small to identify beetle.

6060    Hello,  This little guy was crawling across my bed sheet. He’s about as big as a flax seed, and is brown in colour. Looks like hard shell. He was moving pretty fast.   Late June, Alberta, indoors, house has 2 dogs and an indoor cat. 

Although I cannot place a specific name on this tiny beetle, it at least does not appear to be a pest species that you need worry about. As it is so small, you would need a very good camera in order to get an image sharp enough to show the characters used in identification. Ed Saugstad, retired entomologist; Sinks Grove, WV.

scarab beetle (June bug)

scarab beetle

6059   Hi there. My name is Katelyn and i reside in the city of Port Coquitlam in Vancouver British Columbia.   I’m seeing many of these things in my work, they usually don’t live long I find. Just been seeing them more recently in the past couple weeks when the weather has warmed up. I think they’re coming from outside but I’ve got no clue what these are. Thank you!

This is a type of scarab beetle (Coleoptera: Scarabaeidae) commonly referred to as May beetles or June bugs; their larvae (white grubs) feed primarily on the roots of grasses. The adult beetles are good fliers, and as they are attracted to lights at night, often accidentally wind up indoors. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

Dermestidae beetle larva

Dermestidae beetle larva

6058   Found many in groups all over older house in Warman, SK

This is a larva of a beetle in the family Dermestidae (carpet/hide/skin/larder beetles, etc.), such as a larder beetle (Dermestes lardarius) – see https://tinyurl.com/y9xsabt8 for an image and https://tinyurl.com/j8ergvk for more detailed information.

Wood wasp

6057 Wood wasp

6057   Hi, Quinten here. This was flying around our backyard today….Live in Kamloops, BC

This is a wood wasp (also known as a horntail), Hymenoptera: Siricidae; specifically, it is Urocerus flavicornis. These are harmless to humans; what appears to be a stinger is its ovipositor, used to place its eggs in wood (usually pines) where their larvae develop – see https://tinyurl.com/yakkgfom for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

clear-winged moths

clear-winged moths

6056   I live in Calgary, Alberta, Canada. This photo was recently taken in June 2017 at our local community garden. We have never seen this insect in our garden before. It could be found resting on the leaves of potatoes as well as Shasta Daisies. It looks like a type of wasp, yet we would appreciate having it identified, and also if it is destructive or aggressive. It seemed to be passively resting both times we have seen it. Thank you. Linda

These are clear-winged moths (Lepidoptera: Sesiidae); many species are excellent wasp mimics. Their larvae all are borers in plant tissues, and some, like the peach tree borer, can be serious pests. Ed Saugstad, retired entomologist; Sinks Grove, WV.

redheaded ash borers

redheaded ash borers

6055   Have a pile of logs from a recently cut down tree and saw these bugs on it that looks like wasps from a distance but up close they were more like crickets.

This is a mating pair (the male is the smaller of the two) of redheaded ash borers, Neoclytus acuminatus (Coleoptera: Cerambycidae). See https://tinyurl.com/k8j27rp for more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

jumping spider

jumping spider

6054  My name is Barbara and I live outside of Maders Cove in Nova Scotia.   Four days ago (June 8th) I found this insect on the upholstered headboard of my bed. It has the ability to jump and is 5-6mm in length.  I saw an exact one a few days later in my clear tube bird feeder. After a very bad bite on my neck a week ago I am wondering if it could have come from this insect.  thank you for your work,  Barbara

This is a jumping spider (family Salticidae); it would be very unlikely for it to have bitten you. Ed Saugstad, retired entomologist; Sinks Grove, WV.

wharf borer

wharf borer

6053   This bug is fairly small. Hopefully you can help us identify it. My name is Kat and I’m in Winnipeg, Mb, Canada. Thanks!

This looks like wharf borer, Narcerdes melanura (Coleoptera: Oedemeridae). See https://tinyurl.com/obonjsx for an image and more detailed information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

tussock moth

Tussock moth caterpillar

6052  I don’t know if this is a pest or not but I didn’t want to kill it if it is! Found on raspberry bushes in Calgary, AB on June 20, 2017. Does not seem to be eating the raspberry leaves. May have fallen from nearby apple or spruce. This caterpillar is about 1.5cm long and maybe 3mm wide. It has a tuft on its rear end and the 4 white spots are actually tufts also. I have ruled out a white satin moth but have no idea what else it could be. Any help would be appreciated. Thanks, Melissa

This is a caterpillar of a tussock moth in the genus Orgyia – some of their body hairs reportedly can cause an irritating rash on tender skin.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

Fly Larva ?????

Fly Larva ?????????????

6051   Found this in my dry cleaning shirt. I put it on and few minutes later I realized something bothering me in the back. Took off my shirt and found this. And now I have a what feels like a bite or so…redness…  Ben

 I’m not really sure what this might be – it resembles a fly larva (maggot), but a dry-cleaned shirt would seem to be an unusual place for one of these to be found. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Stink bug

Stink bug

6050  Toronto, our home backs onto the Rouge Park ravine. This little guy was on our sliding glass door. Bonnie

This is a stink bug (Hemiptera/Heteroptera: Pentatomidae); it appears to be the species Banasa dimidiata  see https://tinyurl.com/ycgkje77 for an image and more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

 

Mayfly

Mayfly

6049  Calgary, Alberta, Canada June 08. Has 3 things out its tail, I know it’s not a pest but I’m curious what it is. Thanks,  Braedon 

This is a mayfly (order Ephemeroptera); possibly a subimago that recently has emerged from its naiad (immature) ‘skin.’ If so, it will molt once more to reach the adult (imago) stage. Mayflies are the only insects known to shed their ‘skin’ after attaining the winged stage. Ed Saugstad, retired entomologist; Sinks Grove, WV.

metallic wood-boring beetle

metallic wood-boring beetle

6048    Beetle found on a hot day early June, Barrie, Ontario, very good flyer, shimmery copper belly.   Carolyn

This is a metallic wood-boring beetle (Coleoptera: Buprestidae), possibly in the genus Chalcophora; see https://tinyurl.com/ybeug8rl for an example. Larvae of these beetles are known as flat-headed wood borers, and make characteristic oval-shaped tunnels in wood.

Stonefly

Stonefly

6047    We live in Edmonton, Alberta and have lived at location for 25 years and have never seen this Insect before (found 4 in the last 3 days).  We live on the edge of the city with the North Saskatchewan River across the street. The insects have only been seen towards evening. One at dusk and the other 3 late evening (total darkness).  I’ve tried my own searches but can’t find anything similar. My main concern is if they bite !!!  Any information you can provide would be much appreciated.  Thank you,  Shauna

This is a stonefly (order Plecoptera). Their larvae form an important part of the freshwater food web; see http://tinyurl.com/h84682mfor detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

jumping spider

6047   Found this today and people are freaking me out telling me it maybe venomous.   I just want to be sure it’s not.  Thank you!  Makakita.

This is Phidippus audax, a very common and widespread species of jumping spider (family Salticidae) known as the bold or daring jumper. Like the vast majority of spiders, it has venom glands and therefore can be considered venomous. However, these are not at all dangerous to humans. See https://tinyurl.com/yaxwjyp8 for images and much more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Aphid (plant louse)

Aphid (plant louse)

6046  I recently found these bugs on the new growth of our Mugo Pine here in Calgary. These bugs always appear surrounded by a number of ants and are about 3mm long.    Thank you,  Tom

This is an aphid, also known as a plant louse (Hemiptera/Sternorrhyncha: Aphididae). When feeding, they often secrete a sticky fluid called honeydew; some species of ants are attracted to this substance and will appear to guard the aphids against other predatory/parasitic insects. Ed Saugstad, retired entomologist; Sinks Grove, WV.

firefly

firefly

6045    Hello, I am from Ottawa Ontario Canada and I have been finding these bugs in my back yard, they seem to be growing in numbers and I would like to know what they are called. I have never seen these bugs before and I would like to know more about them. Thank you.

This is a firefly (Coleoptera: Lampyridae); it looks like Lucidota atra, known as the black firefly. See https://tinyurl.com/y7j963c7 for an image and more information on fireflies in general. Ed Saugstad, retired entomologist; Sinks Grove, WV.

wharf borer

wharf borer

6044   Hi can you please identify this bug. Found two or three in the last couple of days. Worried about it being a cockroach. Thanking you. 

This appears to be a wharf borer, Narcerdes melanura (Coleoptera: Oedemeridae). See https://tinyurl.com/obonjsx for an image and more detailed information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

horsebean longhorn beetle

horsebean longhorn beetle

6043  This bug flew in over our patio table while we were having a conversation. We live in the Phoenix Arizona area and have never seen an insect like this ever before. Do you have any idea what this is?  Thanks, Adam

This is a horsebean longhorn beetle, Trachyderes mandibularis (Coleoptera: Cerambycidae). See https://tinyurl.com/yc3petgs for images and more detailed information.  Ed Saugstad, retired entomologist; Sinks Grove, WV.

thread-waisted wasp

Mud dauber wasp

6041  Geographical location: Calgary, Alberta.   Relevant information: Found indoors [top floor of a condominium unit]  Season: Summer, warm and sunny weather.  Insect size: ¾ of an inch to 1 ½ inches [found in our condo last summer and this summer, starting in the month of June each year)  The insects NEVER go further into our unit than the bedroom and appear to die shortly after coming into our bedroom—they rarely fly around, and are often found of the floor beside our large bedroom windows. We have no idea how they are getting into the unit (windows are well sealed and these insects are BIG—but they may be coming in through our air ventilation vents, and perhaps this journey into the building and into our unit is what caused them to die to quickly after entering). Any identification information which can be provided would be greatly appreciated; I believe it’s a parasitic wasp (a beneficial ‘pest’), but I of course could be wrong!   Thanks in advance,  Michelle

This is a thread-waisted wasp (Hymenoptera: Sphecidae) in the genus Sceliphron; it might be S. caementarium, known as the black and yellow mud dauber. See https://tinyurl.com/q9ldqnb for an image and more detailed information. Ed Saugstad, retired entomologist; Sinks Grove, WV.

tortoise beetle

tortoise beetle

6040   I found this bug clinging to the patio screen door from the inside.    It has wings and when it was upside down it opened its wings to turn  itself around. It appears to have a clear scan like outer shell.   Please advise on what this is. Thank you.   Lisa,  Woodstock,Ontario 

This is a tortoise beetle (Coleoptera: Chrysomelidae; subfamily Cassidinae). It appears to be Plagiometriona clavata, known as the clavate tortoise beetle; see https://tinyurl.com/2emdkpo for an image. Ed Saugstad, retired entomologist; Sinks Grove, WV.

Aphid

Aphid

6039   There are lots of these bugs all over our cedar deck and wood patio door trim. A couple days ago they were a pale lime green and now they look like this. Not sure if they are termites or not. Also, the pine tree over the deck has seemed to spray down some sap over the past couple weeks not sure if that is related. We live in Toronto, Canada. 

This is an aphid, also known as a plant louse (Hemiptera/Sternorrhyncha: Aphididae). When feeding, they often secrete a sticky fluid called honeydew; this might be the ‘sap spray’ that you noticed. Ed Saugstad, retired entomologist; Sinks Grove, WV.

assassin bug

Masked hunter bug bite

6038     Hello, I am located in Scarbrough Ontario. This bug bit me in my bed . It stung so bad it felt like razor blades for about 5 min. After it bit me it flipped over and was stunned on its back . I don’t see it on any Canadian bug charts or your charts. Should I be concerned? Is it a kissing bug?   What should I do?

This is an assassin bug (Hemiptera/Heteroptera: Reduviidae) known as the masked hunter (Reduvius personata). These are reported as having a very painful but not dangerous bite (they do not vector any human pathogens). See http://tinyurl.com/23g4bdy for more detailed information.
