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?

My Diptera observations (and other living forms) can be found here, and corrections or comments over there would also be appreciated.

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 Cheers, Lorin Font Color All requests are from the urban area of Vienna, if not otherwise stated.
