Ichneumon

The insects of the Ichneumon family have long,slender bodies, long ovipositors and long antennae.

Ichneumon flies are solitary insects, and most are parasitoids—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.

An insect known as the pigeon horntail (Tremex columba) deposits its eggs, by means of a strong, piercing ovipositor, half an inch deep in the trunk wood of growing trees. Female uses ovipositor to bore through bark into wood, depositing 1 slender egg in each hole. Eggs are covered with fungal spores from a special pocket in female's abdomen. After depositing the last egg, the female often dies without removing its ovipositor from the wood. The dead female becomes food for some insectivorous animal.
