Moved from Hemipenthes.

This is actually an Anthrax species, specifically A. georgicus (often called A. analis). The hairs on the antenna of this species are very small, and can be difficult to see even under a microscope. A much easier character to separate Anthrax from Hemipenthes is to look at the side of the thorax between the wing base and the halter - this area is bare in Anthrax and covered with hair in Hemipenthes (you can see this, somewhat, in the dorsal shot in this series).

The wing patterns of A. georgicus and Hemipenthes morio are almost identical, although H. morio has lighter spots along the wing crossveins. H. morio also has brownish hairs on the body, while A. georgicus is entirely black (anthrax is the Greek word for coal). A. georgicus is one of the most widespread bombyliids in North America, occurring from the NWT south to Nicaragua, and along both coasts.
