Larval competition in the solitary parasitoid wasp Itoplectis naranyae was studied. When superparasitism occurred, competition took place between 24h and 48h after parasitism. Early instar larvae attacked competitive eggs and larvae and killed them, using the mandibles. The elimination of competitive eggs by larvae could be advantageous for larvae in superparasitism and partly explains why superparasitism has no effect on the fitness of surviving larvae.
