I found this rather small Bibio-like fly against one of our outside walls at Leerdam, Netherlands, today. Length appr. 8 mm. Could this be female Dilophus? And if so, could the species perhaps be determined from these photos?

Thanks for any help in advance!

Yes, Dilophus female for sure, the difference with Bibio lays in the end of the fore tibia. In Dilophus there are a lot of smaller spines, in Bibio there is one big hook!
