Pharmacophagy in insects: Ecological and evolutionary perspectives on the non‐nutritional use of plant specialized metabolites

open access: yesEntomologia Experimentalis et Applicata, Volume 173, Issue 7, Page 661-673, July 2025.
Insects interact with plants not only for nutrition but also to actively seek plant specialized metabolites (PSMs) for chemical defense, reproduction, and self‐medication—a behavior known as pharmacophagy. This review examines how insects across diverse orders acquire PSMs from both food and non‐food plants for non‐nutritional benefits.
