Andrenosoma fulvicaudum

Andrenosoma fulvicaudum
Chub Sandhill Natural Area Preserve, Sussex County, Virginia, USA
June 8, 2016

Yes, it often seems that way
Yes, it often seems that way generally everywhere they occur: scarce or scattered. However, Andrenosoma are creatures of recently dead or dying trees; if you find an abundance of such trees, your chances of finding these guys greatly improves! Especially so if your dead trees have attracted fresh Buprestidae!

In Calif., coniferous forest fires may attract large numbers of Melanophila buprestids (while the trees are still burning). The presence of such 'bait' is irresistible to Andreno. fulvicaudum, which quickly arrive--in numbers (100's)--to feast. Trees are still smoldering, but are swarming with mating buprestids and mating and feeding asilids. (Andrenosoma have been reared from these trees afterwards...)

If forest fires, etc. are limited, these flies presumably look for individual dead trees (a recent tree fall) as suitable habitat. I am not aware of any reports of from the eastern U.S. on such forest fire/ fly activities; please be aware of opportunities to check further...

Cheers, Eric

Very nice shot Paul !

Thanks Eric. This species seems to be rare or hard to find. This is the only one I have seen in years of field work here.
