Rare (proposed as a future Red Data Book species) on chalky ground, sea cliffs and other rough ground in parts of south-eastern England. Not recorded in Hampshire or on the Isle of Wight to date. Wingspan 13-17 mm. Distinguished from other Eucosma species by the relatively large and well-defined basal patch edged with raised black scales and the lack of an ocellus on the forewing [Bradley]. Larva feeds on flowers and seeds of Dog-rose, living between flowers spun together with silk, over-wintering as a pupa.
