From the characters of Brachypalpus I will name some which are more or less visible in the picture. The head of Brachypalpus is triangular in anterior view, in comparison with closely related Xylota, which have a elliptic head.
The first flagellomere of the antenna is more or less kidney shaped, wider than long. Hind femur greatly enlarged and arcuate.

In fact, this animal can be identified as a female of Brachypalpus oarus I think, because its lower margin of the face is not produced forward beyond level of base of antenna! In the picture it might look as if it is, but that is the angle of view!
Greetings
