Hello,

I observed this Polistes the 4th of June in the north of France. I think of a Polistes biglumis but I don't know the criteria to distinguish it from other species ?

Cordially Maxime

Bonjour Maxime, I think you are right with P. biglumis:

- Malar (cheek - between eye and mandible) black
- Mandible with yellow spot (hard to see, but it is)
- Flagellum dorsally black, ventrally yellow/orange
- Clypeus with black, horizontal bar
- Mesoscutum pubescent

Regards, Eric

Thank you very much for your help, and what other species are possible in my region, I only know biglumis and dominula ?

I think, P. nimpha could be possible, too.
The most obvious difference to biglumis is the yellow malar space.

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
