The body of a female is c. 2 inches (50 mm) long, with an ovipositor c. 4 inches (100 mm) long. Females of the parasitoid wasp Neoneurus vesculus ovipositing in workers of the ant Formica cunicularia. Parasitized white cabbage larvae showing wasp larvae exiting its body, spinning cocoons. Playback at double speed.
The length of adults varies from about 10–20 millimetres (0.39–0.79 in) in males up to 20–40 millimetres (0.79–1.57 in) in the females, plus about 20–40 millimetres (0.79–1.57 in) of the ovipositor. These ichneumon wasps have a thin black body, several whitish spots on the head, thorax, and abdomen and reddish legs.
The wasps, bees, and ants together make up the suborder (and clade) Apocrita, characterized by a constriction between the first and second abdominal segments called a wasp-waist , also involving the fusion of the first abdominal segment to the thorax. Also, the larvae of all Apocrita lack legs, prolegs, or ocelli.
