Mating black blister beetles
Great website you have there – here’s a contribution to your bug love page: these lovely insects swarmed a bush in my back yard in New Maryland, N.B. and proceeded to gorge on the blossoms and have a huge orgy at the same time. The proceedings went on for about 24 hours, after which all the blossoms were gone and everyone went away satisfied! Good thing I didn’t handle any of them as I did not know what they were at the time! Kathy Power

Hi Kathy,
Your wonderful photograph depicts Blister Beetles in the genus Lytta, as evidenced by the bead-like antennae, but we are not certain of the species. Perhaps Eric Eaton can provide the exact species.

bug in baja mexico
Found a couple of these. Suspect they are common but cant find them in my books. Please enlighten me. Thanks

Hi Lonny
This is some species of Blister Beetle from the family Meloidae. It is not a perfect match to the Iron Cross Blister Beetle, but it is probably the same genus, Tegrodera.

New Mexico beetle
On a trip from Oklahoma to the west coast, I came across dozens if not a hundred or two of these beetles alongside I-40 in mid-New Mexico. I have had no success online in finding the ID. I will watch with interest for enlightenment. Thank you,

Hi Betty,
Congratulations on recognizing this as a beetle. It is a Blister Beetle in the genus Megetra.

Arizona Blister Beetle?
I took this several years ago in the middle of the Mojave Desert – miles from anything! I think it’s an Arizona Blister Beetle. He (?) was just sitting there on his butt eating lunch.

Hi John,
BugGuide lists this species, Lytta magister, as having the common name Master Blister Beetle.

big black one in Wyoming
Dear Bugman,
I saw this amazing, tireless creature on the my front porch, and delayed her so I could take some pictures. Our house is on 12 acres outside Cheyenne, Wyoming, and we have Aspen and Blue Spruce in our yard, although most of the land around us is grassy prairie. The bug was about 1.5 inches long and leathery. It looked like a very tough, very big, very pregnant ant to me. Thanks for your assistance in identifying it.

Hi Ellen,
These could well be the finest photos of an Oil Beetle, Meloe angusticollis, one of the Blister Beetles, that we have ever received.

Entomology Student Needs Help!
I’m taking an entomology course at Arizona State University and collected something that has stumped everyone. This beetle was found on a burnt log in the Brown’s Peak Wilderness of the Superstition Mountains, AZ at an altidude of 1933 meters. Coordinates where found are [ 33°41’41.92″N, 111°19’59.42″W ]. Between two Coleoptera keys, the enormous ASU insect collection/museum, a graduate student and a professor of entomology, we could not key this to the *family* level. Possibilities we could key to are *Oedemeridae*, *Meloidae*, and *Cleroidea* – however nothing was definite key wise and going by gestalt using the reference collection we could not find anything similar. For reference, this beetle is 10mm in length. I have attached a couple pictures and have more on my website at: Any ideas? THANKS!!

Hi Jason,
We like this for one of the Checkered Beetles in the family Cleridae. We will check with Eric Eaton to see if he can verify.

Just checked your site from my workplace. The beetle has ME stumped, too. The habitat and behavior (searching dead wood) really does fit for Cleridae, but the shape of the thing says Meloidae. It will likely be one of those two. Clerids tend to be very fast-moving, whereas blister beetles mostly polk along. Too bad we don’t know how this one behaved….If I get any more ideas or, um CLARification (pardon the pun), I’ll let you know.

Ed. Note: (04/23/2007) Eric Eaton just forwarded us these two identifications:
Great pics. This beast is Tricrania stansburyi, the western species of Tricrania. The species in the eastern US is Tricrania sanguinipennis. Andy Cline, CA Dept. Ag. and myself are doing a revision of this genus.
Jeffrey P. Huether

That’s a bee-parasitic Meloid, Tricrania. Not very common.
