Florida, USA, December 12, 2014.

This was posted to BugGuide (http://bugguide.n...ew/1028035) and is reposted here with the photographer's permission.

The name Prosena siberita was suggested. That European species is introduced in America and was only known from northeast USA as of the 1965 catalog of Diptera. The photo is from southern Florida, a subtropical climate that could be considered a transition to the Neotropical region.

The arista is long haired, consistent with Dexiini.

I compared photos here and ended up confused. Is it a variable species (shape of calypters, acrostichals and marginals on tergites)?
