Hi,
this Chaoborus was observed on october 5th at home (north of Yonne department, Burgondy, France). Is it possible to define the species ? C. crystalinus was already observed at the same place but in march, and with a different color (dark). All my thanks for your expertise.

The species of subgenus Chaoborus are hard to distinguish.
