Wingspan 20-26 mm.
Fairly local throughout much of mainland Britain, though absent from some areas, this species is quite similar to S. steinkellneriana, but is generally paler. They also differ slightly in the position of the black markings.
Flying in March and April, the adults are sometimes attracted to light.
The larvae feed inside a folded or rolled leaf of small-leaved lime (Tilia cordata), birch (Betula) or hornbeam (Carpinus).
