Spuleria atra Haworth Pith moth

This local pest is occasionally troublesome on young, unsprayed apple trees. The larvae bore within the new shoots and cause the leaves to wilt and die. Damage is of greatest significance on young trees.

BIOLOGY

The moths fly in July and August, and deposit their eggs singly close to the buds or leaf bases. The eggs hatch in about 2 weeks, and the larvae enter the bark to burrow inside a shoot or spur throughout the autumn and winter. In spring, frass deposits are expelled from the feeding galleries through surface cracks. Larvae complete their development in June and then pupate close to the surface. Adults emerge a few weeks later.
