Common in woodland, downland and scrub throughout much of the British Isles. In Hampshire and on the Isle of Wight widespread and relatively common, although on the Island, restricted to the extreme western end. Wingspan 10-13 mm. Distinguished from
G. internana and
G. compositella by the paler general coloration of the forewing, the narrow, larger and more strongly curved medio-dorsal blotch and the well-developed ocellus [Bradley]. Larva feeds within seedpods of Bitter Vetchling, Bush Vetch and similar, living between leaves spun together with silk, over-wintering in a cocoon.
