Wingspan 9-10 mm.
Formerly locally resident in parts of southern and central England, this moth seems to have died out as a British species, and has not been reliably encountered since around 1900.
Abroad it is quite common on mainland Europe and eastwards into Asia.
The larva mines the leaves of various roseaceous trees, such as blackthorn (Prunus spinosa) and apple (Malus), forming a gallery leading to a blotch. The pupal cocoon is suspended from silken 'guyropes' and closely resembles that of L. clerkella.
The adult moths fly in September, and overwinter, appearing again in the spring.
