Local on waste ground throughout much of southern England, north to Lancashire. In Hampshire an elusive, uncommon species, with scattered records mainly concentrated in North Hampshire and the south-east. Rarely encountered elsewhere, including the New Forest and the Isle of Wight. Wingspan 10-14 mm. Slightly larger than C. heydeniana, and usually readily distinguished by the presence of a weak pinkish flush to the forewing and the relatively slender median fascia; similar to forms of Falseuncaria degreyana, which lack the pink flush to the forewing, but which are readily recognised by the conspicuous line in the cilia [Bradley]. Larva feeds on flowers of Scented Mayweed, Sea Mayweed, Stinking Chamomile and Goldenrod, over-wintering in a cocoon.
