Recently we saw this fly near a dune area in the Netherlands: Lentevreugd Wassenaar.

Can you help me identifying it?

You can find the picture here:

Looks more like a Tachina. Gonia are at least here strictly vernal species.

Well, Gonia capitata is listed in Peter Tschorsnig's central european key as having records into 'early September', so it is a possibility. The head is difficult to see but the more I look at it, the more it looks like the frons is wide enough for Gonia, so ... without saying it *is* ... I'd say it is possible Smile

Mark van Veen a dutch entomologist thought it might be a Gonia capitata, but he also was very surprised about the date. That?s why I posted it here to find out wheter it could be some other similar species.

To complicate matters: Tschorsnig also mentions in the key that there is yellowish pile on head and abdomen, but in the picture it appears to be rather whitish and that would lead to other species in the key.

It is not Gonia capitata, for one 'reason' because it is not dutch !

Paul had a good suggestion, it is in the Tachininae Tachinini.

Though it cannot be seen for sure from this picture, given the locality I have no doubt that it actually is Peleteria rubescens (or whatever the modern name is of our Peleteria, = nigricornis).
It has some large bristles on the face.
It is quite common in the dune area, but otherwise rare.

It is a bit unclear to me now. Is it Peleteria rubescens, is it Peleteria nigricornis or is it Nigricornis rubescens? I have another picture from the front. I could ask my friend who took the pictures for me if we could upload these as well.

Are there anywhere on the internet pictures of this Peleteria??

Sorry for the confusion.

It is (at least, that is my guess)

Peleteria rubescens,

which has been known as P. nigricornis in the older literature.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
