Hi,
This
Thereva female has black spots on frons disconnected so not the common
Thereva nobilitata.
Could it be
Thereva oculata ?
Belgium, 25-05-2012.about 11 mm.

It is a weird species. To notice a remarkable point, the fron femora seem red.
I agree the specimen keys out to Th. oculata.
I do not have any experience with this species.
It would be the first record for Belgium, at least according to faunaeur.org.
I think a real expert needs to verify this.

Thanks a lot Theo.
I've received a confirmation from a specialist of the Therevidae: it's a female of
Thereva oculata.
