Antennae distinctive: scape lengthened, expanded and densely haired; pedicel short; basal flagellomere kidney-shaped, either concave or convex (as here) along anterior margin below arista; dorsal arista.

Antenna of Drosophila sp. It seems that this type of antenna (arista plumose with dorsal and ventral rays) may be characteristic (diagnostic?) for Drosophilidae.

If you want a real challenge, how about doing your magic on a psychodid ?

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"?)

Thanks Tony, so not diagnostic but maybe a useful character.
Looking at some drawings I see that Periscelidae and Asteiidae have similar antennae.

Phil: just waiting for a Psychodid to fly into my net; none coming out of my drainsGrin
