Hi,
Found this bug in a forest in Quebec (Canada). The city is called Mandeville. It was near a waterfall.
Can you identify it?
Thanks

Eastern Ironclad Beetle

Eastern Ironclad Beetle

Dear Steve,
Thanks to its resemblance to our familiar western Diabolical Ironclad Beetle, we quickly identified your Eastern Ironclad Beetle,
Phellopsis obcordata, thanks to images posted on Bugguide where it states they are found:  “under bark of decaying hardwoods & conifers in association with polypore fungi (Piptoporus, Fomes) in dense boreal forests and at high elevation in Appalachian Mts; larvae feed inside fungi.”

Hello! While backpacking at Cottonwood Canyon State Park in N/Central Oregon (E of the Cascades) this past weekend I found this beetle. Saw at least three of them. It is a sandy/dry location, lots of sagebrush.
Perhaps in the Carabidae (ground beetle) family? The gold accents really stand out. No one seems to know what it is and Google is failing me! Hoping you can assist. Thanks!

Possibly Darkling Beetle

Dune Beetle

Dear Audrey,
We are certain that this is not a Ground Beetle, but we are not certain of its exact identity.  We believe it is most likely a Darkling Beetle in the family Tenebrionidae or a Leaf Beetle in the family Chrysomelidae, but alas, we are in a rush this morning and we don’t have time to research its exact identity.  We are posting your image and perhaps one of our readers will write in with an identity.  If not, we will continue the research tomorrow.

Eric Eaton confirms Darkling Beetle
Hi, Daniel:
It is a darkling beetle called a “dune beetle,” in the genus Coelus.  Never saw one of these when I lived out there.  Neat find!
Eric

Thanks Eric,
We are linking to the BugGuide page on the genus.  Checking out the comments, we do believe it appears more like a member of the genus
Eusattus, and in our opinion, based on images posted to BugGuide, it looks closest to Eusattus muricatus, a species with a much greater range than other members of the genus.

Eric Eaton responds
Well, shoot, I don’t know.  I never saw Eusattus out there, either, though in Arizona and here in Colorado, Eusattus is most definitely most abundant in the *fall*, not the spring.
Eric

Awesome!! I struggled trying to find any information on this beetle! Thank you for your help!!
Audrey

Would it be called the tok tokkie beetle ? What is the scientific name ?

Tok-Tokkie

Dear A Traveler,
According to Beetles in the Bush:  “‘Tok-tokkie’ refers not to a particular genus or tribe of tenebrionids, but rather a number of flightless species that have developed a unique “tapping” method of communication between males and females.  The name “tok-tokkie” is onomatopoeic, referring to the sound these beetles make when they tap their abdomen on the ground.  In the same way that fireflies have species-specific patterns of flashes, different species of tok-tokkies tap with differing frequencies.  The beetle makes the noise by raising its abdomen and then bringing it down on the surface of the ground several times in quick succession.  Males initiate the tapping and await a response from a receptive female.  Signals are exchanged back and forth until, eventually, the two locate each other and mate.  Females lay eggs in shallow excavations in the dry, sandy soil, and the larvae that hatch feed within the soil on the roots of small plants.”
  Your individual is a Darkling Beetle in the family Tenebrionidae, so the name Tok-Tokkie is appropriate.  We cannot say for certain the exact species.

Two other images you submitted are also flightless Tenebrionids, so they can also be called Tok-Tokkies.

What’s that bug,
I found this little guy crawling up the outside wall of my house in Bulverde, Texas in early October. He was about 1-2 inches long, six legs, black and white pattern on his body. I was just wondering what he might be and thought these photos might be helpful to you.
Thanks!

Ironclad Beetle

Ironclad Beetle

Dear Kelsey,
This Ironclad Beetle,
 Zopherus nodulosus, gets its common name because of its extremely hard, nearly impenetrable exoskeleton.

Desert Stink Beetle

Desert Stink Beetle

Dear virusmanbob,
This is a Desert Stink Beetle in the genus
Eleodes.  They are sometimes called Acrobat Beetles because of the way they position themselves when threatened, with head lowered and rear end up in the air.  You can view additional images on BugGuide.

Dear Daniel –
This is awesome!  Thank you so much!
This is my first query to whatsthatbug and it works!
On my website, I posted your reply with attribution and a link to whatsthatbug:

I am a frequent mushroom observer user and I am hooked on that as well.
Best, Bob

Hi,
I don’t know much about entoemology and generally find the answers to my questions of what’s that bug from my family and friends. This time however I’ve not managed to find an answer and google hasn’t yielded any results. I would very much like to know what this is so I can stop traipsing the internet for an answer.

Hairy Backed Pie Dish Beetle

Hairy Backed Pie Dish Beetle

Hi Chez,
Many years ago, we received a similar image that we identified as a Pie Dish Beetle, but it took us five more years to identify it to the species level.  We believe you have submitted an image of a Hairy Backed Pie Dish Beetle,
Helea perforata.

Hairy Backed Pie Dish Beetle

There are many more images online now than there were when we first were asked to identify this unusual Darkling Beetle, and now you can find great images on Friends of Queens Park Bushland where it states:  “Pie-dish beetles feed on dead and decaying plant material.  Pie-dish beetles lay their eggs in moist soil during summer and autumn, usually under clumps of rotting plant material, under which adults often shelter. Females of some species can lay up to 1,000 eggs during their life spans. The rate of egg production appears to be related to temperature. So is the time of hatching, which ranges from seven to fourteen days after the eggs were laid.
After hatching, the larvae can be found in loose clusters on the top of moist soil, dispersing as they develop. When fully grown, they burrow deeper into wetter soil where they build a circular pupal chamber and change into pupae. One to three weeks later, the adults emerge. At first they are soft and light brown, but they harden after about a week and the body becomes dark brown or black, the colour depending on the species. Soon after emergence, mating occurs and eggs develop three or four weeks later. Adult pie-dish beetles can be relatively long-lived (up to a year).”  Esperance Blog has an image of a mating pair of Hairy Backed Pie Dish Beetles.  Your comprehensive views of the individual you encountered are an excellent addition to our photo archive.

Yay!,
Thats an awesome name for a beetle and makes sense, we’ve recently built a compost bin by the house for our food scraps so I look forward to seeing more of these curious creatures wandering around the general area.
Thankyou very much
Chez
