Prunus padus
The larvae feed on cherry plum ("Prunus cerasifera"), European plum ("Prunus domestica"), bird cherry ("Prunus padus") and blackthorn ("Prunus spinosa"). They mine the leaves of their host plant creating a lower-surface, strongly inflated tentifom mine between to side veins. The lower epidermis is folded. Pupation takes place in a white cocoon and the frass is deposited in a corner of the mine.
