parasitoid

This term is a technical biological classification used to distinguish specific organisms from true parasites. While a parasite typically relies on a host for nutrients without necessarily killing it, a parasitoid is defined by the inevitable death of the host, usually occurring when the larvae reach maturity.

In scientific discourse, the word functions both as a noun to identify the organism and as an adjective to describe the nature of the biological interaction. It is primarily used in entomology and ecology, and is rarely encountered in casual conversation unless discussing pest control or natural history.
