Spanish:
Son insectos hymenopteros que dependen, con el Braconidae, de la superfamilia del Ichneumonoidea. Son insectos sobre todo entomófagos, utilizados a veces en lucha biológica. Esta gran familia comprende 35 subfamilias que agrupan más 60'000 especies. Son caracterizados por la nervadura de las alas: la célula discoïdale y la célula cubital se fusionan en una gran célula discoïdocubital con otra célula. Las antenas son largas en numerosos artículos. El taladro es a veces muy largo. Su tamaño generalmente se incluye entre 5 y 20 mm., es generalmente de 10 mm. Su color es a menudo oscura a negro.





English:
Ichneumonidae is a family within the insect Order Hymenoptera. Insects in this family are commonly called ichneumon flies, ichneumon wasps, or simply ichneumons. Ichneumon wasps are important parasitoids of other insects. Common hosts are larvae and pupae of Coleoptera, Hymenoptera, and Lepidoptera.
They differ from the wasps that sting (Aculeata: Vespoidea and Apoidea) in that the antennae have more segments; typically 16 or more, whereas the others have 13 or fewer.
Female ichneumons frequently exhibit an ovipositor longer than their body. Ovipositors and stingers are homologous structures; some Ichneumons inject venom along with the egg, but they do not use the ovipositor as a stinger, per se, except in the subfamily Ophioninae. Stingers in aculeate Hymenoptera are used exclusively for defense; they cannot be used as egg-laying equipment.
Males do not possess stingers/ovipositors in either lineage.
Some species of ichneumon wasps lay their eggs in the ground, but most inject them directly into a host's body, typically into a larva or pupa.
In some of the largest species, in the genera Megarhyssa and Rhyssa, both sexes will wander over the surface of logs, and tree trunks, tapping with their antennae. Each sex does so for a different reason; females are 'listening' for wood boring larvae of the horntail wasps (hymenopteran family Siricidae) upon which to lay eggs, males are listening for emerging females with which to mate. Upon sensing the vibrations emitted by such a wood-boring insect larva, the female wasp will drill her ovipositor into the substrate until it reaches the cavity wherein lies the larva. She then injects an egg through the hollow tube into the poor unfortunate's home. There the egg will hatch and the resulting larva will devour its host before emergence.

French:
Ce sont des insectes hyménoptères térébrants relevant, avec les Braconidae, de la super-famille des Ichneumonoidea. Ce sont avant tout des insectes entomophages, utilisés parfois en lutte biologique. Cette grande famille comprend 35 sous-familles regroupant plus de 60'000 espèces.
Ils sont caractérisés par la nervation alaire : la cellule discoïdale et la cellule cubitale sont fusionnées en une grande cellule discoïdocubitale, avec une autre cellule, l'aréole.
Les antennes sont longues à nombreux articles. Le pétiole est souvent géniculé. La tarière est parfois très longue. Leur taille est le plus souvent comprise entre 5 et 20 mm, elle est généralement de 10 mm. Leur couleur est souvent sombre à noir.
