I seem unable to identify this fly satisfactorily even to family level. Can anyone help? About 7 mm long, taken in the Netherlands in October. Louis Boumans attached the following image:  [137.21Kb] Edited by Louis Boumans on 16-10-2009 11:26 |

I think Heleomyzidae

Thanks, Nikita & Andre, Acc to my key (Oosterbroek et al.) Heleomyzidae should have 2 facial setae. But I think I dismissed Calyptrata too eagerly, and André is right: Scatophagidae is not such a bad idea.. |

The antennae don't look very scathophagid-like to me. I would change the title to "Heleomyzidae ?" to attract the attention of Andrzej.

Hmm, it should be verified with a key :-) Not Heleomyzid but an another family member ! I will find time tomorrow to verify it familiar status ! Maybe similar to Pseudopomyzidae ? Andrzej dr. A. J. Woznica, Institute of Environmental Biology, Wroclaw University of Environmental & Life Sciences |

How about a teneral male of Palloptera ustulata? It is about the correct time to find the first males of this species again. Louis actually suggested Pallopteridae to me earlier.

My first hunch also was to write Opomyzoidea... I would exclude Heleomyzidae because I don't see the characteristic longer setae on the front of the wing. |

Yes, well it actually keys out as Pallopteridae, and I was sure it was sth like a sister species to P. ustulata. But as JW in another forum at first thought it wasn't, and JW knows everything about Dutch Pallopteridae, I was quickly convinced it had to be sth else .. Now this option is back again. In fact it's overall appearance is quite like P. ustulata but I don't think it is this species. I have no Pallopteridae key at hand and my private collection only has females. I see following differences between my females ustulata and this specimen; the latter has: - no trace of apical spot - slight darkening of crossveins - scutum and scutellum concolourous (scutellum yellow in ustulata) - darker wing veins and legs - different fine setation of face and legs (but large setae on thorax very similar) I attach another picture of the scutellum.

A few days ago I wrote "How about a teneral male of Palloptera ustulata". What I meant to write was "How about teneral male ofPalloptera scutellata. Today I found a male of this species in my beer trap which makes me think even more that we are here dealing with a teneral male of P. scutellata.

Aaargh! Yes of course, I should have thought of this myself! I was actually looking for this species, and found this specimen not far from where I found scutellata last year. In this teneral male the apical spot is still completely absent. Thanks, JW! |
