Hello

Here I show a robbery fly which eats a fellow. Which species are to be seen on the picture??? The photo arose in West-Germany in an old oak forest (15.07.2006). Both flies were very big and strong.
Who can help me?

Greetings
Markus

These are Eutolmus rufibarbis females. This is a species normally associated with heathland and other sandy areas in Britain, but it also occurs in open woodland. The ovipositor shape is quite distinctive.
Another stunning shot - brilliant! Wink

@Tony: What do you think about Dysmachus trigonus (Meigen, 1804)?

Hi Markus
Dysmachus has much longer bristles on the hind margin of the tergites, and on the thorax. Also in Dysmachus most of the large leg bristles are white, not black. The ovipositor is certainly similar to Eutolmus, but there are differences in shape which are evident in the photo.

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
