Biology
The eggs are oval, light yellow for the summer generation and milky-white or orange for over-wintering eggs. The larva is yellowish with a shiny brown head. The pupa is 8–9 mm (0.31–0.35 in) long. Hatching caterpillars in spring eat fruit buds. Later they tie leaves into bundles with the help of webbing that they spin. They can skeletonize young leaves and also do damage to buds, flowers, ovaries and unripe fruits. In spring, eggs are laid in large batches. Moths of summer generations lay eggs one by one or in small batches of three to six eggs on leaves, petioles and shoots. Over-wintering eggs are found close to fruit buds.
