Long, very narrow corridor that may wind several times through the leaf, freely crossing the midrib. The corridor often cuts off parts of the leaf, that die as a result. The corridor does not increase in width, until it abruptly widens into an irregular elongate blotch. In the end of the blotch an oval excision is made, c. 4 mm long, in which the larva drops to the ground for pupation. Mines in the very youngest leaves.
Betula humilis, nana, pendula, pubescens.
Mines are found in May – August (Heath & Pelham-Clinton, 1976a).
BE recorded (Phegea, 2009).
