Exenterus amictorius
Exenterus amictorius is an ichneumonid parasitoid wasp introduced to North America that attacks sawfly larvae (Hymenoptera: Diprionidae), particularly during the pre-spinning eonymph stage. The species exhibits adaptive host discrimination behavior that changes during the host's spinning period, lacks discrimination initially but rapidly acquires and maintains this ability. It shows strong positive density-dependent responses to host abundance and has established successfully on multiple diprionid hosts across North America. In multiparasitism situations with the native E. diprionis, E. amictorius consistently survives due to faster larval development.
