Hello! These 15 mm long flies were rather abundant on tree trunks here in Ostwestfalen/Germany in April/May last year (wood with mostly beeches), but I'm still not sure about the family. Could they be Xylophagidae and maybe the one above a male, that below a female of the same genus/species (perhaps Xylophagus compeditus)? Thanks for any hints!

Xylophagus is right. There has been some confusion on the names of the two (?) species occurring in Germany. I'll have to look itup. Theo |

The only other species I know from here in Ostwestfalen is X. ater, but I don't have the "Entomofauna germanica" volume on Diptera yet. Some checklists also mention X. cinctus.

It has now been resolved as follows: X. ater = X. compeditus (British use of these names was correct) X. kowarzi = X. ater auct. nec. (as used by most non-British authors) At least in North Europe X. ater (ex-compeditus) is by far the only common species of this genus and X. kowarzi is a rarity found only(?) in old-growth forests. The flies above are clearly X. ater. Edited by Kahis on 27-01-2006 08:20 Kahis |

The flies above are clearly X. ater. Thanks for the explanations. Then the "Catalogue of the Diptera of Bavaria" (*) is wrong. It lists three species: Xylophagidae: BARTAK 1998; SCHACHT 1994 Xylophagus ater Meigen, 1804 Xylophagus cinctus (DeGeer, 1776) Xylophagus compeditus Meigen, 1820 (*) http://www.zsm.mw...dipcat.htm (long list, use Ctrl-F to go to Xylophagus) Best regards, Jürgen -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= Juergen Peters Borgholzhausen, Germany WWW: http://insektenfo... -=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-= |
