Specimens in nature



The larva mines the leaves of the food plant, at first a gallery in which the frass is deposited in an irregular line in the middle. Later the larva changes to another leaf and causes a blotch. Sometimes several larvae occupy the same leaf, the blotches merge into one big blotch, occupying the entire leaf surface. When the larvae leave the mine, the leaf turns brownish.
Full-grown larvae pupate in a whitish cocoon attached to a leaf or to leaf litter on the ground, occasionally inside the mine.
The species hibernates in the adult stage. Adults hide in thatch, houses, hollows and other shelters.
