Authority:(Herrich-Schäffer, 1855)

Nationally scarce (Nb) in woodland, scrub and river-banks in parts of south-eastern England, with records north to Lancashire. The first British record was made in 1969 by the late D.W.H. Ffennell, who found mines in the leaves of Goat Willow along the Winchester by-pass. In Hampshire still rare, mostly in the south-east of the county. First recorded on the Isle of Wight in 1977 and again at Bouldnor in 2001, but not since. Wingspan 7-8 mm. Similar to P. salicicolella, which see for differences; weakly marked specimens resemble P. salictella in shape and colouring but the strigulae are more distinct (MBGBI Vol 2). Imago comes to light, but just as likely to be recorded in the larval stage, when mines are relatively easy to find where they are present. Larva mines leaves of Goat Willow, over-wintering as a pupa in a cocoon.
