Hello,

In the P?rigord (south of France), 2008/VII/23, 270 masl, size: 22-25mm (really huge like a Vespa crabro !!).

I don't know whether the species has holoptic eyes. Anyway, I saw several specimens in a few days and some of them had a very territorial behaviour, chasing from their territory (a square of thristles) other Diptera (mainly Eristalini), but also Hymenoptera (wild bees) and even Lepidoptera.

Thanks for your comments.
The photo on flicker is awesome!!

I've found a picture of M. crabroniformis in Matile's book and it seems that the eyes of this species are not holoptic. The painting by S?guy shows a female with a space between eyes which is broader than on my picture.

Btw, I'm not sure that the picture already in the gallery is really a female.

Hello,

Found a photo showing the eyes of the male.
The contact point is very low.

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
