Thank you Andrzej ''The postvertical setae are divergent'', it took me some time but I think I found them  I have illustrate them with some arrows. (I am right?) It is not Heleomyzidae?, what kind of fly could it be else?

In a former thread Kahis wrote about Suillia: The five dorsocentral setae (per row) is a good character for this genus: 1 before the suture and 4 behind. I see only 4 setae in one row...Here my wisdom ends! Regards, Sundew |

Hi Kahis, I cannot find Eurygnathomyia sp. in the dutch specieslist. Under Pallopteridae I find 9 Palloptera sp.: 1. ambusta 2. modesta 3. muliebris 4. quinquemaculata 5. saltuum 6. trimacula 7. umbellatarum 8. usta 9. ustulata Eurygnathomyia sp. got preapical bristles, Palloptera does not(that's what I read..) Maybe it is not possible to check these from these details, but next to the apical bristles I don't see 'the preapicals' (maybe you don't see them because they are behind te legs on the picture) But I give them a try..

It could be Palloptera scutellata - just recently added to the dutch list. It could be a male and if it is a male it would be an interesting record because there have been only females been recorded in the Netherlands and in Germany before. Jens-Hermann |

That would be great! It would be nice if someone could confirm this or help me any further, if possible.. I don't have keys for determination for these species. Looking to Palloptera-species in the diptera Gallery(checking the obvious wingpatterns) and to the time in the year when these flies are active, two species I cannot check: P. ambusta and P. modesta.

It seems to me Jens-Hermann is right: Palloptera scutellata.

This specimen keys out to scutellata , which is the only member of the genus (in Britain) with the combination of unmarked wing apex plus greyish marks elsewhere on the wing.Martin Martin Harvey |

Wow! , that's nice I've read that the fly was catched in 2003, and also in 2004 and 2005. And only females where found?! (http://library.wur.nl/WebQuery/gkn/lang/1845147) Is the differerence between male and female visible from these pictures? |

A rather late response, but it looks like a male specimen to me. I hope John will also have a look and will give his opinion.
