Wingspan c. 10-12mm.
This rare and highly localised species is only known from three locations in the British Isles. It occurs on the limestone of the Burren, Co. Cork; in woodland in Kent, and has also been found in north Hampshire, on downland.
The larval foodplants are goldenrod (Solidago), and daisy (Bellis perennis). The larva feeds from a case, typical of the genus, creating visible feeding blotches on the leaves.
Adult moths are quite attractive, marked with white lines on a yellowish-ochre ground colour. They fly between June and August.
