Hi, Some days ago I was in a wood in southern Brandenburg, where I saw this medium-sized fly that looked muscid-ish but had a petiole untypical for that family. The rounded head made me think of Rhinophoridae; however, the calypters are quite big. So a Tachinid is left - and I do not know which... Help is appreciated! Thanks, Sundew Sundew attached the following image:  [188.21Kb] |

Definitely Estheria, I'd say E. bohemani. Theo |

Hmmm - I had a E. bohemani once (http://www.dipter...pid=140513) and it had a very conspicuous, quite dark, wing venation... The fly under concern has a much less "visible" wing venation independent of light and camera angle. Then, in Tschorsnig & Herting 1994 I read that in Estheria the dorsal excavation of tergite 2 reaches the margin. This seems not to be the case in my fly. Can you please inform me a bit more in detail why this is an Estheria for sure - does the petiolate venation beat the other characters? I add one more picture. Thanks!

The head profile and long legs indicate Dexiini. Of course, you always have to rethink about Microphthalmini, ibut it it clearly neither Microphthalma nor Dexiosoma. The wing venation with such a long stalk leads in Europe then directly to Estheria. The bare parafacial, dark scutellum, long stalk and 4 DC all indicate Estheria bohemani. I just checked my collection: all my bohemani are at least somewhat yellowish. I agree that this one seems to be a bit more yellowish. Maybe the light, maybe variation. I have no doubt this is bohemani, are we sure about the other one ? Theo |

Yep - it is the same individual  . So the excavation of tergite 2 is deep enough? To me, it does not reach the hind margin... |
