Microplitis croceipes (Cresson) exhibited facultative (arrhenotokous) parthenogenesis. Unmated females produced all male offspring, while mated females produced both sexes at varying ratios but generally at a 1:1 ratio. Females of various ages mated successfully. The lifespan of the females ranged from 5 to 15 days at about 26. Their average oviposition capacity was about 300, and they demonstrated no ability to discriminate larvae which had been parasitized previously.
