    Where smooth leaved willows are present.

    When to see it

    Adult moths are at large in two generations, in July and from September through to April. The overwintering adults are sometimes found in thatch or haystacks. Larval mines are best looked for in June, or in August/September.

    Life History

    The larva feeds on willow, particularly on Purple Willow and sometimes on other smooth-leaved willows, such as Crack-willow.  The larva mines in the lower epidermis, forming a translucent mine, then moves into the twig via the petiole, eventually returning to a second leaf.
