Life Cycle
Most are Megaspilidae are ectoparasitoids of concealed hosts in cocoons or puparia. Some Dendrocerus species are hyperparasitoids of aphids: they attack endoparasitoids of aphids, such as larvae of aphidiine braconids. While many Dendrocerus species attack a wide variety of hosts, some specialize on certain predators or parasitoids.(2)
