Food Plant: Sorbus aucuparia (Rowan), S.aria (Common whitebeam), S.intermedia (Swedish Whitebeam), S.torminalis (Wild service-tree), Malus spp. (Apple)

Egg: Underside of leaf

Mine: July; August - September

Notes: Initially makes a subrectangular blotch and eats through to the upper epidermis - turning it brown. It then makes a typical Parornix fold at the leaf edge or spins a silken pad in the centre of the leaf. This causes the leaf to arch up (as shown) and the larva eats through to the upper epidermis - turning it brown. Widespread throughout the UK. Mine shown is on S.intermedia.
