Eupelmus
This is a female E. (Eupelmus) vesicularis (Retzius) (Eupelmidae: Eupelminae). The species apparently was introduced from Europe on the earliest ships in straw. Both sexes occur in Europe but in North America it is parthenogenetic, i.e. reproduces asexually so there are only females. Makes it easy to be introduced. Females are not very particular in what they attack and this species has one of the largest host ranges known for a chalcidoid. Another characteristic that makes introductions easy. Females are also short-winged, but this specimen has shorter wings than normal. The apex of the fore wing seems to be missing, normally there is a right-angle bend with the apical part about the same length as the basal part that remains. The fold is a line of weakness along which the wings often break-off for some reason.
