Hello flyforum,
I am trying to find the name for this Bibio sp. (male)
Also found in the Amsterdam Woodforest.
It's got a dark (black) pterostigma and on the frontal leg it has got two red spines (one big).
The metatars 3 is long and in my opinion small..
Long hairs on the thorax, difficult to see what color, I think they are white/yellow.
(on the picture there is much contrast because of backlight so it seems to be black I think)
Perhabs someone can help me any further with these Bibio?
With some doubts I came to B. lanigerus, B. varipes, B. Johannis
greeting, Robert

Well, my guess would be
B.johannis - those body hairs look black to me.

Hello Chris,
Yes, you are right. On other pictures I can see the black bodyhair and metatarsers 3 better.
These fits with B. Johannis!
Thank you for answering
Robert,

with such a really black stigma, I have no doubt it is johannis.
lanigerus is, in NL, restricted to sandy soils, though very common there. Johannis also occured on peaty soils, clays, ...
