Dear forum,

today I found these two parasitic wasps in a box in which I've reared caterpillars of Thaumetopoea processionea and Lymantria dispar last year. I also reared Phalera bucephala in this box, but I collected those as eggs and they are still intact pupae, so I do not think they served as host.
I sit possible to identify these flies from the photos, or if necessary with the collected specimen?
