Chaoborus requires genital dissection?
smol
Netherlands, 2023-10-18, near lake

Am I correct to say that Chaoborus of the flavicans-complex, or now called subgenus Chaoborus, require genital dissection to properly ID?
This would be Chaoborus crystallinus/flavicans for NL I believe.

There are some non-genital differences between the species, but the characters are variable and difficult to see in photos. I would always recommend dissection to be certain.

Ah, thank you very much Tony Irwin! I did read something about differences in the tergal bands, but nothing conclusive. Then I will skip these species for now until I will catch them Smile
