The species exhibits the family's characteristic elongated 'neck' between head and thorax, enlarged hind tibiae, and long ovipositor in females. As a parasitoid of solitary bees, the female uses her ovipositor to deposit eggs in host nests. The species belongs to a genus of approximately 500 species worldwide, with at least 15 species documented in North America.
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 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.
