Common on dry pastures and waste ground throughout southern England and southern Wales, north to Yorkshire. In Hampshire the species is widely distributed, but not particularly common. Recorded on the Isle of Wight for the first time since 1900 at Freshwater in 2010. Wingspan 11-16 mm. Similar to
C. atricapitana, in which the head and labial palpus are blackish grey, and
C. hybridella, in which the thorax is white (blackish in
C. dubitana). Larva feeds within flowers of Common Ragwort, Rough Hawk's-beard, Smooth Hawk's-beard and Goldenrod, over-wintering in a cocoon.
