Common on waste ground and dry grassland throughout much of the British Isles, more numerous on the coast. In Hampshire and on the Isle of Wight common and widespread. Wingspan 24-29 mm. separated from similar species by numerous longitudinal black streaks emanating from central area of disc, closely following venation, most terminating at fascia at three-quarters, a few passing through but always finishing before termen (MBGBI Vol 4 part 1). The imago overwinters, and may be found in man-made habitat such as thatch, stables and outhouses. Larva feeds on flowers and seeds of Wild Parsnip and Hogweed, living gregariously within spun or rolled leaves.
