Bagrada Bug

Feeding and life cycle

Bagrada hilaris is a plant-feeding stink bug strongly associated with brassicaceous crops and weeds. Both nymphs and adults feed, so crop damage is not restricted to the adult stage. Development proceeds from egg through nymphal stages to adult, without a pupal stage. Host availability and weather influence population activity. Reports of severe damage elsewhere establish a potential pathway of impact, not a measured loss for Kauaʻi.
