Dear members,
Oxyna parietina or flavippennis I suppose.
Nr.1: 7.5.09
Nr.2: 15.5.09
Nr 3: 5.7.09
all of them garden in Lower Austria, near Vienna.
Thank You
Margarita Auer

Lieber Margarita:
Your pictures are a real riddle for me: the flies do not look
parietina, and from my almost 35 years of experience with tephritids I never collected that species beyond June or May: it seems to be univoltine.
I do not have many
nebulosa in my collection, and I use to collect them on Leucanthemum daisies, which they use as host plants, inducing rhizome galls similar to those of O. flavipennis.
In all, the two latter species are rather overlapping in its wing pattern an its variability, and the setae on its notum do not give an ansewer: apical scutellar seta is present, like in flavipennis, but the presutural dorsocentral setae characteristical for tht species are not visible or rather absent...
Anyway, this could be some poorly known aspect of its natural history, and I am curious to hear more of this story in the future.
Stay in touch with flies and me!

Dear Valery,
Thanks a lot for Your detailed answer concerning this riddle.
Of course I will keep an eye on these flies and will remain in touch with You.
When You want to know something in special tell me please.

Mea culpa!
It was really my fault: I considered "09" as "September".
Actually, the first two from May are parietina, and the third (which according to my previous posting "does not look parietina" ) from July is a typical flavipennis. So the riddle was just in my inaccurate reading of the data.
