Antenna of Drosophila sp. It seems that this type of antenna (arista plumose with dorsal and ventral rays) may be characteristic (diagnostic?) for Drosophilidae.
The characteristic feature of many drosophilid antennae is the terminal fork - it's difficult to decide whether the dorsal or ventral bit of the fork is the main stem of the arista. Other flies have dorsal and ventral rays, but the end of the arista is obviously a single process, not forked. (though I think Periscelidae may be another "fork-ended family"?)
