Like other members of the genus, this species is very difficult to identify as an adult, and genitalia examination is recommended to be certain.
However, the larval mine characteristics are quite distinctive, and in this case, the foodplant is hawthorn (
Crataegus
). In its later stages, the larva folds over a leaf lobe to form a diagnostic cone.
The adult moths are on the wing in two generations, during April and May and again in August. The species is very common throughout the British Isles.
