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!

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

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

Jewelm699 - did you upload it to a forum (which one?) or the gallery? I can't find it.

I’m hoping someone can identify the phoridae maggot or pupae I just uploaded.

Rafael p is legs and f1 is fore femur

If you experienced a very sluggish site recently, it may have been because someone tried to upload a maliciuous script by force. It appears to have failed. The visitor was blocked further access.

@Paul Beuk Thanks mate!! Best wishes!

Where are the meaning abbreviations of Lindner's series Die Fliegen der Palaearktischen Region, ie. f1: anterior femur, ...and what about "p"? (I don't possess volume I)

17.07.19 19:37
Yup, you can view the wing from above (dorsal side) and from beneath (ventral side).

Hey Dipterists! Quick Question: Vein r2+3 bare beneath. I've always assumed that this is below as in when you look at the wing flat. Am I right? Thank youuuuu! Pfft
