Macalla thrysisalis This caterpillar is the larval stage of a tiny moth that lays its eggs on bougainvillea leaves. After hatching, the caterpillar feeds on the leaves and completes its development into the adult stage in 4 to 5 weeks. Several generations are produced during the year, with the greatest infestations occurring in late spring.
Apply an insecticide labeled for bougainvillea caterpillar, following directions on the label.
