15 spp. in a single genus in our area(1), 1500-2000 spp. worldwide (Jennings and Austin 2002), of which ~500 are described (Jennings & Deans 2004)

Abdomen slender, very long, and attached to thorax on upper (dorsal) side. Hind tibia expanded. Ovipositor very long. Head is set on a "neck", differentiating from ichneumons.(2)

Larvae are predators or predators-inquilines (consume larval food, not the larvae) of other Hymenoptera that nest in twigs and in wood (Jennings & Deans 2004)
Adults feed at flowers, especially those of the carrot family, Apiaceae. (Townes, p.120)
