Hi,

Center of France 17th of april 2022 near a pool.
When I saw this Eristalis on the screen I noticed that something was sticking out under the tergite 4.
Has anyone heard of stepsipterans parasitizing syrphidae.
Unfortunately I don't have any more precise pictures.

This looks like mechanical damage to me - a bird, perhaps?

OK Tony, probably the reason why it was not very active.
