Caterpillar
The caterpillar is white to pale green with black dots, the head, neck and anal shield are black.
Bionomics
The larva feeds between spun leaves on the host plant and feeds on the inner surfaces of the leaves, causing window-like patches but not eating the outer epidermis. When fully fed it spins a cocoon under bark, in rotten wood or in an old spongy oak-apple gall, including those which have fallen. It may pupate in autumn or overwinter as a larva.
The adults are on the wing from late afternoon into the evening and later come occasionally to light.
Flight periods
The adults have been seen from late March towards late May.
Observed on
- Host plant (genera):
