Hello everybody,

I took this photo in the middle of June this year.
It was at a small pond in the northern part of Germany near Flensburg.

I think it is a Dioctria-species. Can anyone confirm this and is it maybe possible to identify the species?

Thanks in advance and best regards,
Mario

PS: It´s the only picture I have!

Perhaps better to say nothing, but I think it is D. hyalipennis. But it is years ago since I collected a robberfly
