A glass jar full of jammed horse-chestnut leaves was brought to me on July 11, 2010 by a security man from my work who returned from Bryansk region (close to the Ukrainian border). He said that his car was all covered with small moths or something. A few small wasps have subsequently emerged in this jar. Size around 2 mm.

That's what I believe to be a male of the same (considerably smaller, escaped).

Dear Black, I have just seen your photos. The parasitoid specimens belong surely to Pnigalio genus (Eulophidae), for my experience they would be Pnigalio mediterraneus but to be sure I would have the specimens. Do you think would be possible to send me some specimens? At moment I am studying this genus so I would be happy to have your specimens. |
