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?
Regards,
Ectemnius
