Chalcidoidea (parasitoids) - (chalcid wasps)

This is a large superfamily of mainly beneficial wasps and includes both primary parasitoids as well as hyperparasitoids of insect pests. Many are endoparasitoids but others are ectoparasitoids. There are more than 20,000 species in the superfamily and many are important biological control agents, are commercially reared and are regularly used against agricultural pests.

The adults are usually less than 5 mm long and often have a metallic colouration. The antennae are elbowed, the head and thorax are broad in relation to the abdomen. The wing venation is very reduced. The larvae have a reduced head and 13 trunk segments.
