Females of light brown apple moths lay eggs on the upper surface of the leaves. Eggs hatch into small larvae within 8- 10 days. After hatching from eggs, young larvae start feeding on the leaves, buds and small fruits until they mature. Mature larvae may spin a silken cocoon around them or roll the portion of leaf and then pupate inside the cocoon or rolls. Adults emerge from the pupae within 10- 20 days, mate, lay eggs and life cycle continues. Depending on the favourable conditions, light brown apple moths can complete 2- 4 generations in a year.
