Berlin - May 2018

finally found a Hippoboscidae just sitting on a wooden post at the garbage area of my apartment building. I could only make a few bad flash photos. I use f16 indoors with flash which works nicely but f11 with flash is required outdoors. I didn't have time to change settings.

I can see 8 scutellar bristles, so this should be Ornithomya avicularia, correct?
I have a specimen but i will wait to examine it.

Thank you for your time.

i've blown up the scutellum to show that 8 hairs are visible.

Yes it is avicularia.

wing venation is characteristic.

Thank you, Theo. I appreciate your help :)

By the way, this is a male. I've looked at it a bit in the microscope. I see the claws and the pulvilli but what is the feather-like object called? does this piece even have a name? I suppose the purpose of it is for clinging to a host? or perhaps a sex comb? vide attachment with red arrow.
