Thread subject: Diptera.info :: Oxyna parietina? => yes

Hello.

This fly is from 11 May from near Neuss (west germany). For me the wings look like Oxyna parietina, but I never saw this species with such a black body.

What is it? (Wing length about 4 mm, body length about 5 mm without ovipositor.)

Thanks,
Michael

No doubts, O. parietina. Central Europe has 3 species only, and May is the season for O. parietina, which oviposits into young shoots of Artemisia vulgaris. The females of other two species have very datk wings with less small yellow dots,
The body of fresh specimens looks ash gray due to whitich microtrichia, but this specimen is greezy (and has some setae broken), but I rely on the season and wing pattern. The 3 species also differ in the shepe of ovipositor aculeus shape (seen at 40x of a compound microscope).

Thank you for the quick reply. I found it indeed while beating beetles from an Artemisia bush.
