It danced around on my patio made of Lark and ended up dancing on Glechoma hederacea. Bigger than the Sepsis (who behaves like that) I usually see. Yesterday Jutland near Silkeborg, Denmark Erik Nielsen attached the following image:  [98.88Kb] Edited by Erik Nielsen on 31-08-2010 09:14 |

Somehow reminds me of a tachinid!?

Female of Melanophora roralis (Rhinophoridae).

I begin to have doubts about my previous ID. Abdomen has a strange shape, vein R4+5 end at wing apex, not above as in M. roralis. So it could be a Tachinid just like Jan suggested, like a Catharosia ? Another picture could help...

The tachinid specialists will be able to tell more. So it might be good to change the title to attract their attention. Could be Catharosia pygmaea. That's the Catharosia species known from Denmark

Fascinating, and I am not sure. I can see both Melanophora and Catharosia suggestions. Theo |

I bet if it was on a pin then we'd have no problems identifying it

The white calyptra is what makes me doubt Catharosia. In that case, it would be C. albisquama, which is very very VERY small ( 1,8 mm., our smallest Tachinidae). And that does not agree.... If I'd only seen the second pic and Staphane had called it Melanophora, I would have been perfectly satisfied. Maybe I am now .....as well ? Theo |

I'm not convinced both calypters are white. Maybe Erik can upload a detail in higher resolution!?

Just by feeling I would vote for C. pygmea (the calypters are dark enough in the second last pic). |

Given the new information, I tend to agree with Jaakko. The femora are reddish as is often seen in pygmaea (though not always). Apparently the 'white' calyptra was again a trick of the flash, not for the first time, and for the last time neither, I'm afraid. Theo |
