The green-brown caterpillar has a light brown head, the prothoracic plate is pale light brown, the thoracic legs are brown-black and the pinacula are black-grey.


The larva lives between two leaves spun flat together, with the upper one mostly black. Hibernates in the larval stage and pupates in a cocoon in the larval habitation.
The adults live very hidden in the vaccinium bushes but are sometimes active during sunny afternoons towards dusk and later come sparsely to light.
