• Anastatus semiflavidus

  Anastatus semiflavidus is a minute egg parasitoid wasp in the family Eupelmidae. It is a specialist parasitoid of the range caterpillar (Hemileuca oliviae), a pest of rangeland grasses in western North America. The species exhibits arrhenotokous parthenogenesis, with females developing from fertilized eggs and males from unfertilized eggs. Laboratory studies demonstrate strong temperature-dependence in its development and reproduction.
