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 ...? Morten |

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. Morten |

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. Iain MacGowan |

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.  Morten |
