"The ichineumons, with long ovipositors, as the European species, <em>Ichneumon manifestator</em>, seek the burrows of the wood-boring insects, whose larva they are enabled to reach by means of this organ. Each species usually infests a particulat species of insect; and, singular as it may appear, many of these parasitic larvae are again preyed upon by others, whose parents are directed by an unerring instinct to the selection of the proper position for the nourishment of their arguement." &mdash; Goodrich, 1859

The Ichneumonoidea are insects classified in the hymenopteran suborder Apocrita. The super family is made up of the ichneumon wasps (often inaccurately called "ichneumon flies"; family Ichneumonidae) and the braconids (family Braconidae). Like other parasitic wasps, they were long placed in the "Parasitica", variously considered as an infraorder or an unranked clade, but actually not a monophyletic group.

Ichneumon flies are solitary insects, and most are parasitoids&mdash;the larvae feeding on or in another insect which finally dies. As with all hymenopterans, ichneumons are closely related to ants and bees. The female finds a host and lays an egg on, near, or inside the host's body. Upon hatching, the larval ichneumon feeds either externally or internally, killing the host when they themselves are ready to pupate. The large ichneumon fly (Thakessa), with long flexable ovipositor. The various parts of ths ovipositor are spread aapart in the figure; naturally they lie together to form a single piercing organ.

The Seventeen Year Locust (Cicada septendecim) spends seventeen years underground feeding on the roots of trees. On the seventeenth year of its life it burrows out of the ground, cracks its shell and spreads its previously unused wings. It flies to the nearest tree to mate. The female cuts holes in the branches of the tree to deposit her eggs. The males make a very loud drumming noise while they are above ground.

The eyes are simple, one or two on each side of the head. All the species are small, and live parasitically, on human beings, terrestrial mammalia, and birds." &mdash; Chambers, 1881
