Hello,
I found this original little fly in August of this year. It was moving on the low vegetation in a wooded and humid area in Villeneuve d'Ascq (Nord department in France). I had found a fly of the same genus Dolichocephala in May in another environment, in Lille, identified on this site as "D. guttata or oblongoguttata"
https://diptera.info/forum/viewthread.php?forum_id=5&thread_id=113152 but it seems to me that this fly of August belongs to another species : based on the shape, number and distribution of the spots on the wings I think it could rather be the species D. irrorata.
What is your opinion on this ? Thank you in advance.
Dominique
