Thread subject: Diptera.info :: Bibio venosus ♀

Hi, I've found these Bibio this morning in an old deciduous forest. I firstly determined the female:
- Long tibia I - spur < ¼
- Legs dark brown
- Most veins and stigma strongly pigmented
- Hairs whitish
- Eye naked, long oval

The male (a couple of steps away) was prey to a Nigma flavescens - unfortunately only 1 image.
(EDIT: male seems to be not venosus)

What's your opinion? Thanks for any comment!

Greetings, Eric

Hi Eric,

The female is totally OK, of course !
The male, I am not sure. The hind veins are not pronounced.
Could this be leucopterus ?

Hi Theo,

thank you very much for your reply. I've tried to find some more today but it's raining and they hide - I'll try again the next days. Other images without flash are much to bad to see anything - neither the veins nor the tibia I.

Greetings, Eric
