Family Ichneumonidae

Order & Family
Order: Hymenoptera, Family: Ichneumonidae
Size

See this bug in the Encyclopedia

Natural Habitat

Forests, meadows, and gardens, often found near decaying wood, plants, or hosts.

Diet & Feeding

Adults feed on nectar and pollen; larvae are parasitic, feeding on the internal tissues of other insects (such as caterpillars, beetle larvae, and spiders).

Behavior Patterns

Females use their long ovipositors to drill into wood or plant tissues to locate and lay eggs directly inside or on the bodies of host insects. They are solitary and not aggressive toward humans.

Risks & Benefits

Benefits include acting as a natural biocontrol agent by parasitizing and reducing populations of agricultural and forestry pests. They generally pose no risk to humans as they do not sting defensively in the way social wasps do.
