Classification
Kingdom Animalia (Animals)
Phylum Arthropoda (Arthropods)
Subphylum Hexapoda (Hexapods)
Class Insecta (Insects)
Order Hymenoptera (Ants, Bees, Wasps and Sawflies)
No Taxon ("Parasitica" (parasitic Apocrita))
Superfamily Ichneumonoidea (Braconids and Ichneumons)
Family Ichneumonidae (Ichneumon Wasps)
Subfamily Ophioninae
Numbers
32 genera worldwide arranged into 5 genus-groups; 58 spp. in 7 genera north of Mexico (plus 2 synonyms of Eremotylus formerly treated as genera)(1)(2) (Taxapad)
Size
6-29 mm
Identification
Ocelli (usually?) large. Females have a very compressed abdomen and a short, very sharp ovipositor. The ovipositor can penetrate the human skin; most other ichneumons can't 'sting'.

The following characters will identify most Ophioninae (except for a few Eremotylus): Cell 3Cu of fore wing with adventitious vein originating at 2/1A, and parallel to wing margin. Ocelli usually large, with lateral ocelli close to or contiguous with eyes. Body color usually pale brownish-orange, rarely black. Ovipositor short, barely extending beyond metasomal apex (with rare exceptions). Cell 1M+1R1 of fore wing often with area below stigma lacking setae (fenestra) and with sclerotized inclusions. Tarsal claws usually densely pectinate. (Source: Key to the Subfamilies of North and Central American Ichneumonidae By David Wahl http://www.amentinst.org/Subfamily_Key.php)
Range
worldwide(1)
Habitat
Wide range of habitats. Most species are crepuscular or nocturnal, some diurnal. They are known to come to lights.
Food
Solitary koinobiont endoparasitoids of the larvae of other holometabolous insects, mostly Lepidoptera, although a Nearctic species of Ophion is known to parasitize a beetle larva(3); the most usual hosts are moth larvae that feed exposed on vegetation, especially members of Noctuidae, Lasiocampidae, Lymantriidae, Saturniidae, Geometridae, Arctiidae, and Sphingidae.(4)
