RECOGNITION
Description
Slender, wasplike. Two recurrent veins. 2nd submarginal cell small or lacking. Base of cubital vein lacking, 1st submarginal and 1st discoidal cells fused. Resulting vein structure called 'horse head' shape. Antennae with 16 or more segments and usually at least half as long as body. They vary greatly in size and color; many are uniformly colored, from yellowish to black and others are brightly patterned with black and brown or black and yellow; many have middle segments of antennae yellowish or whitish. The majority resemble slender wasps but differ from the stinging wasps (Scolioidea, Vespoidea and Sphecoidea) in having longer antennae with more segments (usually at least 16). Many have long ovipositors, often longer than the body. Ichneumonids are notoriously hard to identify: aside from the sheer number of species, there are numerous cases of distant relatives that appear almost identical. Any identification based solely on comparing images should be treated as suspect unless an expert has said there are no lookalikes for the species or group in question.
Diversity
About 5,000 described species in North America, possibly 3,000 more undescribed; arguably, the largest animal family, with the estimated 60,000 species worldwide (up to 100,000, according to some estimates).

BIOLOGY
Food
Parasitic on other arthropods.
Host
A great variety of hosts (mostly immature stages) is used, though most species attack only a few host types; some infest spiders and other non-insect arthropods.
Habitat
Common almost everywhere.
Distribution
Worldwide
Diversity
About 5,000 described species in North America, possibly 3,000 more undescribed; arguably, the largest animal family, with the estimated 60,000 species worldwide (up to 100,000, according to some estimates).
Active Period
Many hibernate as adults, usually under loose bark of fallen trees.
