 Hi flyforum,

Seperately, but in each area I found these two Dilophus sp.
The typically black wings (by female!), suggest that this is Dilophus febrilis.

But perhabs there are more look-a-like Dilophus with black wings flying around?

 NO. Dark wing is always female febrilis.

 Thank you Theo, for your time and reaction Smile

Female is Dilophus febrilis, the male (last picture) can not be identified as Dilophus febrilis for 100% I think?

But it was in the surrounding, so it is likely..

 Males Dilophus are very difficult.
However, febrilis is very common, and all others are restricted in space and time in the Netherlands.
Start looking end of may for D. femoratus in the dunes !

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
