- Biology

Speckled green fruitworm overwinter as pupa in the soil. Adult moths emerge from pupae early in the March through May. After mating, females lay eggs in masses on the leaves in the canopy. Eggs hatch into small caterpillars that start feeding on the buds, flowers, leaves and fruits. While feeding, caterpillars develop 6 developmental stages and mature. In June, mature larvae drop to the ground and pupate in the soil and life cycle continues. Under favourable conditions, speckled green fruitworm can complete 1 generation in year.
