Rare (proposed as a future Red Data Book species) in chalk downland in parts of Kent. Not recorded in Hampshire or on the Isle of Wight to date. Wingspan 18-24 mm. A larger species than C. straminea, and further distinguished by the presence of scale-tufts in the comparatively broad median fascia [Bradley]. Larva feeds within flowerheads of Greater Knapweed.
