Definition

1. Noun:
   • A type of parasitic wasp: An ichneumon fly is a slender, wasp-like insect belonging to the family Ichneumonidae within the order Hymenoptera. Its larvae are internal parasites, feeding on and eventually killing other insects, particularly caterpillars and the larvae of other insects.

Examples of Usage

• Noun:
  • The gardener identified the ichneumon fly as a beneficial insect for controlling pest populations.
  • An ichneumon fly uses its long ovipositor to lay eggs inside a host caterpillar.

Advanced Usage

• In biological control: The term is often used in entomology and agriculture to describe a natural predator used for pest management.
  • Farmers encourage ichneumon flies as a form of integrated pest management.

Variants and Related Words

• Ichneumonid (noun): A member of the Ichneumonidae family.
• Parasitoid (noun): A broader biological term for an organism, like the ichneumon fly, that lives in or on a host during its larval stage, ultimately killing it.

Synonyms

Notes on Meaning

• Beneficial parasite: While parasitic, it is generally considered beneficial to humans as it helps control populations of herbivorous insects that damage crops.
