Looks OK for
Xylophagus, and seems to fit
cinctus quite well.

Thank you so much, Tony! I read a little cf. out of what you write - or is it an expert's way of telling what species it is ...?

Yes, there is a little cf. ringing in my head. It has all the characters for a
cinctus larva, as given in Stubbs and Drake (British Soldierflies), but AFAIK the larva of
junki is unknown, and I'm not sure which other species might occur in Norway.

Thanks!
4 or 5 Xylophagus species occur in Norway - including X. junki.

Hi Morten
Krivosheina & Mamayev (1972) Ent Rev wash. 51, 258-267 provide an illustrated key to the larvae of the Palearctic Xylophagus species. Your photos seem to fit well with X. cinctus. I ca send you a scan of the relevant pages if you require.

- but as Tony says - the larvae of X. junki has not been described

Thank you, Iain!
It would have been nice to have an illustrated key to the larvae of the Palearctic Xylophagus species. You have my email. :)
