I think you have something spectacular for Belgium: Strongylophthalmyia ustulata. I think unrecorded so far, new family for Belgium. Smile

Hello Eric Steckx,

That is very spectacular! It is indeed a Strongylophthalmyia ustulata. The thirds femur is entirely orange. Last year the species was first observed for the Netherlands. Currently there is a paper in press that reports the family new for the Netherlands.
Would you be interested to co-author a paper reporting this family new for Belgium on account of your photo?

Based on this picture, can we suspect if it's a female or a male ?

Looks like it has an obvious genitalial capsule - so its a male
