... and at last a Stratiomyidae (?) observed in a hollow in an old apple tree, never seen, associated with a lot of very rare beetle species:

Wow, great pictures of a beautiful fly.
This must be in the family Xylophagidae, but I can't tell you what species it might be!
Greetings,

Hello Frank,

Looks more like Xylomyidae (Xylomya maculata ??) to me.

Aha, yes, families that I don't know so well.... :o
But I was close I guess? :D

It does match Xylomya maculata very well. The adults of Xylomyids are seldom seen, but larvae can be rather common in suitable dead trees. 100% of the new records of this family in Finland are by coleopterologists, who tend to spend more time digging in such trees.

oh, you are very fast replying - thank you very much!
I changed the subject twice in a minute ;-)
If I change the family to Xylo... I could offer a second species for diptera.info/gallery: Xylophagus compeditus?

Greetings from a tree digging coleopterologist

The 2nd fly is X. ater (= X. compeditus). The name X. ater was erroneously used for the species now known as X. kowarzi up to the late nineties (the brits got this one right from the beginning).
