Hello,
I found this Chaoboridae in Villeneuve d'Ascq (Nord, France) near a large pond. It was on May 9, 2025.
The fringed appearance of the wingtips and the little genitalia that can be seen may suggest the species Chaoborus obscuripes.
What is your opinion on this ?
Thank you in advance,
Dominique
