By the way it is a female.

In the Netherlands there seems to be another Bibio with a red thorax: Bibio anglicus. How can the Bibio hortulanus and the Bibio anglicus be distinguished?

Hi everyone, Iīm glad to "see" you again :)
I'm sorry I know this is an old post, but I'm wondering the same for long.
Lindner keys say, for isntance, that the female's hairs on thorax are witish in B. anglicus and dark in B. hortulanus, it seems the orange-red colour is not reliable, but Theo pointed at wing venation in an older post; i can see a longer vein r-m in B. anglicus, could it be right?
Thanks in advance

The fork leading to the apical part of the radius is more or less symmetrical in anglicus, whereas it is strongly asymmetrical in hortulanus.

Anglicus is restricted to GB, NL, B? and the very western part of D,
hortulanus is common in the east and south, less so in western Europe.
