Summary
Gasteruptiidae, commonly known as carrot wasps, is a distinctive family within the Apocritan wasps, with around 500 species globally. They are known for their long, slender abdomens and unique life cycle as predators on other insects' larvae.
Physical Characteristics
Abdomen slender and very long, attached to thorax on upper (dorsal) side. Hind tibiae are expanded and club-like. Ovipositor is very long in 12 species, but short in 3 species. The propleura form an elongated "neck". Females commonly have a long ovipositor except in the genus Pseudofoenus.
Identification Tips
Absence of 'teeth' on the crown of the head and somewhat thickened antennae differentiate Gasteruptiidae from the unrelated family Stephanidae.
Habitat
Nests of solitary bees and wasps, as their larvae prey upon host eggs, larvae, and provisions.
Distribution
Widespread distribution worldwide. The genus Gasteruption is global, while Hyptiogaster is endemic to Australia and some species of Pseudofoenus are found in Australia, New Zealand, South America, New Guinea, and the southwest Pacific.
Diet
Adults feed on flower nectar, particularly from Apiaceae. Larvae are predators or predators-inquilines of other Hymenoptera.
Life Cycle
Third instar larvae spin cocoons and overwinter. Pupation occurs in spring.
Reproduction
Females lay eggs in the nests of solitary bees and wasps. Larvae develop by preying on the host's eggs and larvae.
Ecosystem Role
Natural predators of other Hymenoptera, influencing populations of their hosts.
