Hi,

I am collecting adult insects from a lake in southern Germany. I know I have multiple species of chironomids, which I am grouping together (for my own sanity). From previous studies, I also know there are Chaoborus flavicans emerging from the lake.

Does anyone know of any distinguishing features (for both male and female) that could be used to readily separate the C. flavicans from the wide range of chironomids?

I have attached some pictures of (what I believe are) chironomids but if anyone can identify any as C. flavicans, that would be very helpful. Many thanks!
