I wrote 11/19/2015 and at that time only had a photo of the beetle on its back. It appears early in the morning when it’s still cool. It is 4cm long. In winter It appears all day long.
The manuscript librarian said there is another species in the evening that looks like this one but with grey spots on its back. It only appears at night. It walks on the walls and makes holes to sleep inside.
Neither bug eats manuscripts but we are curious as to what it is? Please help.

Darkling Beetle

Darkling Beetle

Dear Michaelle,
Our hunch is that this is a Darkling Beetle in the family Tenebrionidae, but we do not have time to research a more specific identity this evening.  Your beetle does remind us of the Stink Beetles in the genus
Eleodes that we have in the Los Angeles area and desert climates in the Southwest U.S.

Dear Daniel –
Thanks for the information.  I notice the picture is already up on your pages.

Darkling or Ironclad Beetle

Darkling or Ironclad Beetle

Dear Greg,
We haven’t the time to do the research at this moment, but this is either a Darkling Beetle in the family Tenebrionidae or an Ironclad Beetle in the family Zopheridae.  We will do additional research later today.

Update:  December 10, 2015
We believe we found this matching image on iSpot that is identified as a Darkling Beetle, and there is a really robust comment on the differences between Ironclad Beetles and Darkling Beetles that ends with this conclusion:  “I think the teneb in this observation belongs to the tribe Asidini of the subfamily Pimeliinae, but I don’t know the tenebs well at all.”

But of course Daniel.
The small beetle-like insect was walking on the sandy-dusty ground of the Anderson Campsite at Waterberg/Namibia. The ground colour was black and the body was all covered with sand. My idea is, that this “shabby” appearance is perhaps a way to camouflage itself.
After the research I did today, I now think it could be a Mouldy Beetle (Eurychora sp). In the video I made, it sure looks like it. I´ve put my video (20.6 MB) and a pic from the web on my google-drive-account, you can watch it in the link if you like:

That´s all I know until now to image 3, hope it helps.
Thanks again,

Camouflaged Insect

Camouflaged Insect

Thanks for the additional information Becky.  The segmented antennae are a very good indication this is a beetle.  At first glance we thought it was a True Bug, but the antennae structure overrules that.  We found some images of Mouldy Beetles on Margy Green Coleoptera and we believe you have correctly identified this critter.  Images on iSpot and  Africa Wild are also a very good visual match to your image.

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!!

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

Tok-Tokkie

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.
