Gryon pennsylvanicum (parasitoid) (Ashmead, 1893)

This wasp is an egg-parasitiod of several Hemiptera from the family Coreidae like Leptoglossus species . For example, in western Canada it is the most common egg-parasitiod of the western conifer seed bug, Leptoglossus occidentalis, an invasive species in Europe. It is also an important egg-parasitoid of the squash bug, Anasa tristis, accounting for over 98% of all egg-parasitoids collected from that species. In some surveys, the parasitation rate exceeded 50% of the eggs.

G. pennsylvanicum is found in North America, many parts of South America and in Japan. The colour is black with most parts of the legs being yellow.
