Most records are of leaf-mines.
Argus 58, 2009:
VC62. Hutton Rudby, mines on narrow-leaved willow, 5.11.2009 (CHF). NEW VICE-COUNTY RECORD.
2013 (CHF): Less common than the previous species but mines are locally common on rough (long) leaved varieties of willow. The egg can be on either side of the leaf but is usually close to the midrib or leaf margin. The frass line is narrow and leads to a small blotch.
