Dear Forum!
I have always been kept in belief the flies of genus
Phalacrotophora are parasites of
Coccinellidae (i.e. for instance the excellent photos on "Diptera.info"). One sunny day - on
5th of August 2010 - I had gone on my knees at the popple stump and within an hour I
could see very interesting "show":
There were several tiny holes on the stump surface, inside them the nests of crabronid wasps
of genus Diodontus (I am convinced). The females have brought some Homoptera prey time to
time. They were carefully watched by the anthomyiid flies Eustalomyia (hilaris - I think) and
- it is very interesting! - by the phorid Phalacrotophora more!!
If Phalacrotophora is parasite either of wasp or anthomyiid, I donīt know...
I take that this set of photos will tell much more:

Eustalomyia hilaris indeed can be associated with sphecoid wasps and are cleptoparasites in their burrows.
Nice documentary!

I have doubts about the phorid being
Phalacrotophora as that is a ladybird parasitoid. I think it might be a
Megaselia but will try to find out more tomorrow (if I don't forget so don't hold your breath ;), Roger has experiences a smurfish period trying to do that).

Most of the New World Phalacrotophora are parasitoids or kleptoparasites of solitary Hymenoptera, but I'm not sure if there are any European records of this. Nice find! It certainly looks like a Phalacrotophora to me. You didn't catch a specimen, did you?

I must set right the genus name of sphecid wasp: it is
Crossocerus.

Would be interesting to investigate whether they really are congeneric...
