Is this one of the Sarcophagidae? It looks different from the Sarcophaga that I see normally in my garden. I found it a few weeks ago indoors (Bilthoven, Holland). It is 11 mm long.

Well observed. That should be a Macronychia. It even looks like M. striginervis. Any chance you can check the hairs on the backside of the head ? Are those all black or both black and white ? Theo |

The long hairs on top of the head and the smaller ones at the side are all black, as far as I can see, but I'll check it tomorrow, when I have better light. The smaller hairs at the backside, behind the eyes, are (more or less) visible on this photo.

This would have been a perfect photo, if the leg was missing. Are the pulvilli long or short (is it male or female). See you tomorrow Theo |

On the lower part of the back of the head are whitish (silverish) hairs. The pulvilli are inconspicuous: the same length as or shorter than the little claws.

then is looks like a female and it looks like striginervis, as first impression. Female striginervis is very obvious by a strong ovipositor. SO look at its tail. Theo |

I have been looking for its ovipositor, but I can't find it, certainly not something as conspicuous as on this photo ( http://diptera.info/forum/viewthread.php?forum_id=5&thread_id=5141 ), as you can see on the photo I've attached. So I thought I had done something wrong. I checked the characteristics you've mentioned again: it centainly has has whitish hairs on the lower part of the back of its head (silverish isn't a good description, though, on second inspection they look even a bit yellowish) and the pulvilli seem small to me, but perhaps I've judged that wrongly. Could it be a male? Menko Vlaardingerbroek attached the following image:  [157.73Kb] Kind regards Menko Vlaardingerbroek |

You are right, it is a male after all, Difference is difficult to see, so I checked in my collection. BUt striginervis is correct: hairs are indeed yellowish,not whitish, but by no means blackish. So: male Macronychia striginervis Theo |
