Is this the right place to ask members the names of various flies?

Hoi Elck,
The upper photo shows an Empididae, most probably Empis tessellata!
The other photo pictures a Dung fly of the family Scathophagidae, and it could very well be the Golden Dungfly, Scathophaga stercoraria!
Greetings

The right place is where I have moved the thread to: Identification queries | Diptera (adults)

Well, it is not Empis tessellata. The fork in the posterior radial vein (R4+5) is absent, so it must be a species of Rhamphomyia. The colour pattern in the wing makes me think of R. cinerascens, of which the females have a partly darkened base of the wing. However, the first question I should then ask is 'when was the picture taken?'.

The picture was taken on april 11th at 17:43 hours

(Is it possible that because the message was moved I did not get email notification of the answer?)

Then I stick with my identification of R. cinerascens.

And there is no email notification (yet?) for replies in the forum so you should check yourself. ;)
