[Syrphidae] Re: Cheilosia with strange things growing on face

[Rodgeir K-son]

Hello

One of our most specialized orchid flower, Ophrys insectifera, only attracts “Grabwespen” males of the genera Gorytes and Argogorytes for its pollination.
The”Grapwespen” can then be seen flying with these 'pollines' in their face. Just a wonderful evolutionary “right fit!”

Ämne: [Syrphidae] Cheilosia with strange things growing on face


Dear all,



Last June I collected a few Cheilosia in the Alps with weird things growing on their face. Something like a fungus or so. Have a look at a picture of an unfortunate lady Cheilosia rhynchops affected by it: https://observation.org/observation/198290575/.



Does anybody have an idea what this is?



Best wishes,



Sander
