Hello

Today I photographed a dung fly(?) on a blossom of a blackthorn "Prunus spinosa" (West-Germany). Unfortunately I do not know, which Species is that. This species was very little...I think 5-6mm. Who can help me and identify this fly?

Thanx a lot.-)

Scatophaga sp, I think. Nikita V will probably tell you more Wink

1. Crex, I'm not at all Scathophagidae expert!
2. But I think it isn't Scathophaga stercoraria. Such spring and small species may be Scathophaga decipens or Scathophaga obscura.

I'm sure, it isn't Scathophaga stercoraria. This species is very grey... the bigness from Scathophaga stercoraria is 2x or 3x.
I don't know Scathophaga decipens and Scathophaga obscuraSad

Thanx Nikita... perhaps another specialist writes some more!

@Crex: Thanx (Danke)

best regards
Markus

Perhaps not, sorry 'bout that, but you usually answer questions about Scatophaga and for that we are grateful. I think you are as close to an expert one can come without actually being one Wink

Nice photo Markus!

I think it is Scathophaga stercoraria (L.)

I am no expert, but every Scathophaga stercoraria that I saw and photographed, was considerably hairier and looked in their entire appearance considerably larger and stronger. Maybe this fly was as big only half as a normal Scathophaga stercoraria was. With the unaided eye I could not identify it her as a dung fly because she was too small.

This postal address and the foto-link shows a Scathophaga stercoraria.

How can one explain so big differences? I have some doubt.

Thanks OzerovWink

best regards

1. To my excuse (I thought it isn't S. stercoraria) I can say that Andrey spend about 15 min before coming to conclusion that it is S. stercoraria. Scathophaga decipens and Scathophaga obscura both has femorae dusting on basal 2/3-4/5, but never completely.
2. S.stercoraria is very variable species, there are boxes in Moscow Zool Museum with hundreds very different specimens of S.stercoraria - yellow and grey, hairy and bold, small and large... So, believ, S.stercoraria is really the best possible answer!

And what would be the criteria of some other species of this genus?
I seem to remerber something about yello antennae...
Just to know something better...
