Adults emerge during December and January and eggs are laid singly, generally on the upper surface of the new season’s larger leaves. The newly hatched larva constructs a shelter on the upper surface of the leaf by up-ending and hinging a leaf disc cut from the edge of the leaf. The larva secures the disc to the leaf with silk. Larvae remain in their shelters until mid to late winter with little feeding taking place during this period. Larvae become more active during the spring, emerging from the shelter at night to feed on the leaf. Larger larvae form twisted cylindrical shelters out of single leaves. The leaf of the shelter dies but the base of the petiole is fastened to the twig with silk, preventing the shelter from falling. Larvae pupate within the shelter. At Buchan only one generation is completed each year. The large conspicuous adult is fast flying and they perch on leaves in sunny positions with their wings wide-spread.
