Hello,

while photgraphing bees on flowers of Prunus laurocerasus, flies of this species attacked several times bees - at least it look like that.
I would like to know, which species it is.

Germany, near Cologne, 2019-04-20.

Thank you!
Thomas

Conopidae, Myopa or near. "The known larvae of all Conopinae, Myopinae, and Dalmanniinae are internal parasites of aculeate Hymenoptera, which the ovipositing females attack in flight." (Smith and Peterson in Manual of Nearctic Diptera)

Thank you, John!
Myopa sp. looks good - I have never heard about these parasites of bees.#

Thanks again
Thomas

In Myopa, many species are pretty similar. This one seems to have the scutum totally black, also just in frint of scutellum, which would suggest polystigma
