Hi,
I tried to raise
Phytomyza aquilegiae (also to answer my question in this
this thread myself, as nobody could help me out so far :)).
Was a little bit late in the year already I guess, so from all the leaves I checked I could only find one where nothing yet had hatched. I kept it for some days until I realized a hymenopteran pupa within the leaf, so I had no hopes of getting a fly out...
Eventually I spotted a tiny wasp in the glass where I kept the leaf, but upon opening saw an even smaller second one.
Questions I have:
- which family/families do they belong to (Eulophidae? Trichogrammatidae?)
- did they both develop in flies or could one be a hyperparasite?
- is there a person known studying these kinds of wasps?

Stegmaier, 1972 (Parasitic Hymenoptera Bred from the Family Agromyzidae (Diptera) with Special Reference to South Florida - The Florida Entomologist, 55(4): 273-282) cites the following Eulophidae for
Ph. aquilegia:
Closterocerus tricinctus, Derostenus variipes, Zagrammosoma multilineatum

Thanks Dmitry. Not sure if those Florida species have a holarctic distribution. In addition, UKflymines lists the following species:
Chrysocharis amyite (Walker, 1839) Eulophidae: Entedoninae
Chrysocharis orbicularis (Nees, 1834) Eulophidae: Entedoninae
Chrysocharis pentheus (Walker, 1839) Eulophidae: Entedoninae
Closterocerus trifasciatus Westwood, 1833 Eulophidae: Entedoninae
Neochrysocharis formosus (Westwood, 1833) Eulophidae: Entedoninae
However, it is hard to get trustworthy and reliable images of these species, to begin with. And then, there is still a high risk of confusion.
I will keep the specimens, in case I will find s.o. interested in them :)
