I still have a problem to distinguish these species. This one definitelly doesn't have yellow hairs on the abdomen, but I have seen L. ephippium the abodmen of which looked much darker. Are there some other important characteristics? Slovakia, Great Fatra mts., 600 m.a.s.l., forested valey Thank you in advance Matej PS: I have quite many pictures of this specimen, I can send some slightly different views, however, I didnţ manage to photograph terminalia too well. treebeard attached the following image:  [261.65Kb] |

This is Laphria flava (or at least one of its relatives) to me. Laphria epphippium never has bands of pale hair on the abdomen. |

In this case i have my doubts.... i think it may depend on lightfall and individual variability..... i think the hair is too short and sparse for flava... :-) in Spain it seems to look like this sometimes: http://www.biodiversidadvirtual.org/insectarium/Laphria-ephippium-(Fabricius-1781)-img770007.search.html But males of ephippium do have brown hair along the hind margins of the tergites. A male flava would have much more yellowish white hair on the head and in mystax.For the rest this creature looks much too dark for flava. So, in my opinion this is a male ephippium with some lighter coloured hair on the abdomen.

And I was convinced this was a darkish Laphria flava... Shame on me!  But the link speak volumes. You have convinced me  But it is shameful that I saw it clearly in the link but not in this case

Thank both of you again. It is somehow satisfactory to see that it is not so easy even for much more experienced people  |
