Today I found two flies, which are I think Aslilidae.
I have no experience with this kind of flies.
To be honest, I never saw one before.
So I hope this is Asilidae sp.!
And it would be great to know what specie this is :)
On the wing there was a little shining green/purple
length: ~10 mm
greetings Robert,

No luck this time;) This critter belongs to Bibionidae - March flies.

I could have known this..:@, I spent some time on these flies some days ago..
In early spring this could be B. Johannis.
I see a dark pterostigma, but is it black or brown..?
The light hairs on the thorax makes me think of B. Lanigerus..
On another picture I can see clearly a big spine on the frontal leg, this means that it is a Bibio sp. anyway!
On the frontal leg the metatars 3 = small and long, Bibio varipes could be the specie.
Also the time of flying and the biotope (woodforest) fits..
I believe it is Bibio varipes :)
But the legs of this male are not black?!, which I have seen on other pictures of B. Varipes..
greets, Robert :)

Difficult to see the pterostigma clearly but with pale hairs on the thorax and pale tibiae I would guess is is
B.lanigerus.

Hello Chris,
Yesterday I found a mistake in my determination of this fly.
For the metatarsers (3!) I looked to the wrong leg(it's the third leg and not the frontleg)
That together with a dark pterostigma, whiite hairs, big red spines makes B. langerus a better candidate!
Thanks again for your reaction :)
