Chrysobothris femorata (Olivier) - Chrysobothris femorata - Male
McMinnville, Warren County, Tennessee, USA
June 3, 2006
Size: 11 mm
C. femorata have antennae that are yellowish-green and become reddish toward the apex. Unlike C. adelpha, the clypeus( upper lip ) of C. femorata is more rounded. The common name is Flat-headed Appletree borer, FHAB. They range in size from 7.5-16mm and feed on many fruit and forest hardwood trees. This one was collected on oak.

Species complex.
Chrysobothris femorata is considered a 'species complex' as I have come to understand it, with several 'cryptic' species not easily identified. Perhaps some are even undescribed?

Chrysobothris femorata
That is true, but C. femorata can be pulled out from the group. Males are the easiest to pull out by using genetalia pics and other key characters, females are a different ballgame. I have well over a hundred specimens in our lab collection (over 3000 specimens) that are det to the complex, mostly females.

Joshua is right...
...Unfortunately the characters that distinguish C. femorata from it's relatives don't show well in this specimen - namely the distinctly cupreous elytral apices and more abruptly narrowed posteriolateral margins of the elytra.
