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.

Interesante imagen de un insecto tan pequeño pero que con tu buen hacer consigues acercarlo de una manera fantástica.
Un saludo, JL.

Very interesting insect and a well composed shot, Nicolas.
Both the flowers and the insect complement each other in this lovely shot.

Hello Nicolas,
a well composed and beautifully coloured picture. Furthermore, I like to see a specimen of a rarely presented insect group and the crab spider just below the wasp.
Best wishes, Peter

Hello Nicolas,
Excellent image. The diffused light worked perfectly here. I admire the colour of the plants as well as the unusal iridescent purple on the ichneuomid.
Best greetings and TFS!
Michal

Magnifique détails , beaucoup de netteté.
Bravo
Marie
