Hello,
I photographied this fly on June 1, 2025, in Villeneuve d'Ascq (Nord department in France). It was near a pond and a small stream. I only managed to get one profile photo.
I think it is a Muscidae but I am having trouble identifying the genus. On Le Monde des Insectes someone suggested
Hydrotaea or
Hebecnema. Could it be one of these or another genus ?
As for the sex, you can't tell from the photo, but the eyes are wide apart so it is a female.
Thank you in advance for your opinion,
Dominique
