 Repeatedly observed in the SE-Netherlands: diptera (possibly Sphaerocidae?) feeding on preys of spiders such as in the attached picture (honey bee Apis mellifera predated by crab spider Misumena vatia). Is it possible to ID the flies at some level? Has this behavior been described somewhere? Do they just feed?

I post the picture with consent of the author P. van Breugel

Thanks in advance for your help.

Best regards,
Annemiek van Dijk

 Hi Annemiek, I think, these are Milichiidae, possibly Desmometopa.
Greetings, Eric Kloeckner

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
