Gasteruptiidae
Carrot Wasps
Gasteruptiidae is a family of apocritan wasps comprising approximately 500 species in two subfamilies (Gasteruptiinae and Hyptiogastrinae) and six extant genera worldwide. Members are commonly known as "carrot wasps" due to their slender, elongated bodies and frequent association with umbelliferous flowers. The family is characterized by a pronounced elongated "neck" (propleura) between the head and thorax, a petiole attached high on the propodeum, and notably swollen, club-like hind tibiae. These wasps are parasitoids or predator-inquilines of solitary bees and wasps, with females using their long ovipositors to deposit eggs in host nests.
Gasteruption
carrot wasps
Gasteruption is a genus of parasitoid wasps commonly known as "carrot wasps" due to their slender, elongated bodies and frequent association with umbelliferous flowers. The genus comprises approximately 64 species worldwide, with 21 species recorded in Central Europe and at least 15 in North America. Adults are characterized by a pronounced "neck" between the head and thorax, an abdomen attached high on the thorax, and enlarged hind tibiae that function in flight dynamics and vibrational sensing. Females possess long ovipositors for accessing host nests. Larvae are predator-inquilines in the nests of solitary bees and wasps.
Gasteruption assectator
wild carrot wasp
Gasteruption assectator, commonly known as the wild carrot wasp, is a species of carrot wasp in the family Gasteruptiidae. It is a generalist inquiline parasitoid that targets multiple bee and wasp species including Hylaeus confusus, Hylaeus pectoralis, and Pemphredon fabricii. The species exhibits the distinctive elongated neck and enlarged hind tibiae characteristic of its family. Adults are frequently observed at flowers, particularly umbelliferous blooms.
Gasteruption kaweahense
Gasteruption kaweahense is a species of parasitoid wasp in the family Gasteruptiidae, commonly known as carrot wasps. Like congeners, it possesses the family's distinctive enlarged hind tibiae and elongated neck. The species is known from limited observations. As with other gasteruptiids, females likely parasitize larvae of solitary bees by depositing eggs into host nests using a long ovipositor.
Gasteruption kirbii
Gasteruption kirbii is a species of parasitoid wasp in the family Gasteruptiidae, commonly known as "carrot wasps." Members of this genus are characterized by an elongated neck between the head and thorax, a high abdominal attachment point, and notably enlarged hind tibiae. The species is one of at least fifteen Gasteruption species in North America, with five occurring in the eastern United States and Canada. Like other gasteruptiids, it is presumed to parasitize larvae of solitary bees nesting in twigs or wood borings.
Gasteruption tarsatorium
Carrot Wasp
Gasteruption tarsatorium is a species of carrot wasp in the family Gasteruptiidae. It is characterized by an extremely slender body, elongated neck, and enlarged hind tibiae that function in flight dynamics and vibrational sensing. The species is a parasitoid of solitary bees and wasps that nest in twigs or wood borings. Females possess a long ovipositor to access host nests.
Gasteruption visaliae
Carrot Wasp
Gasteruption visaliae is a species of parasitoid wasp in the family Gasteruptiidae, commonly known as carrot wasps. The species exhibits the distinctive family traits of an elongated neck, slender body, and enlarged hind tibiae. Like other gasteruptiids, it is presumed to parasitize solitary bees and wasps nesting in twigs or wood borings, though specific host records for this species remain limited. Females possess a long ovipositor for accessing host nests.
