Pristaulacus fasciatus
Pristaulacus fasciatus is a species of aulacid wasp in the family Aulacidae, found in North America. These parasitoid wasps target wood-boring beetle larvae, particularly longhorned beetles (Cerambycidae) and jewel beetles (Buprestidae), as well as wood wasps in the family Xiphydriidae. Females are larger than males, averaging around 16 mm in body length compared to 13 mm for males. The species is rarely encountered but can be found by searching cut wood and logs where their hosts occur.
