Similar species:
Forewing: 4.5 to 5mm
Habitats: Downland, scrub, woodland rides and clearings, marshes and fens.
Habits: The moth occasionally comes to light.
Foodplant: The larva's first instar is in a winding gallery mine on the lower side of a leaf of Perforate St John's-wort, Slender St John's Wort, Hairy St John's-wort or Square-stemmed St John's Wort. This mine is later enlarged into a blotch which contorts the leaf. The larva then spins one or two successive, downward pointing cones from the tip of the leaf. It pupates in a cocoon in a folded leaf on the ground.
