Ichneumon wasp

Ichneumon wasps are a large family of parasitoid wasps in the order Hymenoptera.

Ichneumon wasps are a large family of parasitoid wasps in the order Hymenoptera. They are among the most diverse insect groups, with tens of thousands of described species and many more estimated worldwide. Most species are harmless to humans and are ecologically important because their larvae develop on or in other arthropods, often helping control pest populations.

Classification and diversity

Ichneumon wasps are a family of wasps in the order Hymenoptera. They are widely distributed and are considered one of the largest and most diverse animal families.

Life cycle and parasitism

Female ichneumon wasps lay eggs on or in host arthropods, and the larvae feed on the host as they develop. In most cases, the host eventually dies, which is why the group is called parasitoid rather than merely parasitic.

Ecological importance

Many species help regulate insect populations and are useful in natural biological control. They can reduce numbers of insects that damage crops, forests, and other plants.

Human interactions

Ichneumon wasps often look intimidating because of their slender bodies and long ovipositors, but they are usually not dangerous to humans. The ovipositor is used for egg-laying, not stinging.
