Love Bug
Hello Again, I hope all is well. This is a very common insect at the conservation area. The shell is a beautiful copper colour – the photo does not do it justice. Today it was extremely hot and humid and after a brief rain all the insects – moths, butterflies, and everything else that crawls or flies was mating!! Take Care,

Hi Janet,
Though your photograph is lovely, it will have rose growers cringing. The Japanese Beetle, Popillia japonica, was first discovered in New Jersey in 1916, and the introduced species quickly spread throughout the eastern states. The grubs live underground in lawns where they eat grass roots, and adults emerge in mid summer to devour roses, fuschias, and other ornamental blooms.

More unidentified critters
I photographed three of these on recent trips to Arkansas. Hoping you could help me identify them.

Hi again Rus,
We checked with Eric Eaton on your scarab beetle and here is what he wrote back: “If the scarab is from North America, it has to be a male Polyphylla sp. (ten-lined june beetles, though some species lack the stripes).” So you have an Unlined Ten-Line June Beetle.

Large black beetle? Can you help Identify?
My children and I have found a large black beetle on our deck and don’t know if he fell out of the tree or flew to get there, but found it very interesting. They are very interested in finding out what type of bug he is, so can you help us. I am sending some pictures of him to help you out.

This is a Scarab Beetle, and we believe it is the Odor of Leather Beetle, AKA Hermit Flower Beetle, Osmoderma eremicola, which may be confirmed on BugGuide.

Hi, Bugman.
Can you identify the beetle in the attached photos? My dad has a bumper crop of them in his garden, about 30 miles outside of Dallas, TX. Love your site. Thanks for any wisdom you can impart. (My money’s on scarab beetle.)

Hi Amanda,
We wanted to be more specific than just a generic scarab beetle agreement, so we contacted Eric Eaton. He quickly wrote back: “Nice images. These are flower scarabs in the subfamily Cetoninae. They mimic bees, flying with the wing covers closed. This is probably Euphoria kerni, or a related species in that genus. Other possibility is Stephanucha sp., but they are apparently more northern, and also along the Atlantic coast. None of these are pests, just sometimes more abundant than usual. Eric”

Two More Puzzling Specimens
Dear Mr. Marlos?
Thank you very much for identifying my previous mystery insect: the Trichiotinous bee-scarab. It was one of several insects which I have yet to ID. If you and your colleagues would be so kind as to have a crack at naming another two specimens of mine, I would be most pleased. The first, found near my home on Vancouver Island is likely a dung beetle but of an unknown genus (to me). The second, from my region as well, has proven to be even more challenging to ID. I am not even certain of it’s family and I hesitate to call it a scarab even though it exhibits several anatomical features which resemble those of such a beetle. (See attached photos for both.) On a final note, might I request the urls of the best sites in your opinion that may aid me in my quests for further insect identification? This may save me from troubling you with more ID requests in the future. Thanks again,

Rugose Stag Beetle Bolboceras obesas

Dear Sandy,
We always love turning to a real beetle expert, Eric Eaton, with difficult identifications. Here is what he has to say: “Well, as luck would have it, I grew up in the Pacific Northwest, and both these species are familiar to me. Both are males. Females do not have horns. The top [first] image in your e-mail to me is of a rugose stag beetle, Sinodendron rugosum. They are usually found in rotting logs. The second image is of an earth-boring scarab (family Geotrupidae). The species is Bolboceras obesus. Females dig burrows terminating in cells which they provision with fine humus, which serves as food for their offspring (grubs). Neat insects. I’ve never seen one alive, but they are supposedly common. Thank you for sharing.”
Regarding our favorite websites, we recommend Angel Fire and for caterpillars, we like Caterpillars of the Eastern Forests.

A Mysterious Scarab Beetle
Hello, my name is Sandy and I am an insect enthusiast from British Columbia, Canada. I have written to your site (which is doing a wonderful service to the public) because I have failed to identify a particular scarab beetle specimen I have found. It and 2 others were collected on the flowers of a fire weed plant outside of Thunder Bay, Ont. in the summer of 2004. The actual size of the specimen in the photograph is roughly 1 cm. Hopefully the enlargement and the given information will aid you in an identification. Many thanks, I anxiously await your findings.

Hi Sandy,
We wrote to Eric Eaton who is a specialist in beetles and he wrote back to us: “This is a species of [genus] Trichiotinus. They are difficult to ID to species without a key. Good mimics of bees, though.” Our beetle guide says they commonly occur on flowers during the day and readily take flight when disturbed.
