(1/125th sec at f14. © David Hastings) Description Family: Erebidae Wing span: 34 - 46mm This moth is unmistakable, with a long broad red line and two red spots on the forewing, and an all-red hindwing. It can be found in most of the British Isles, but not in northern Scotland. It is most numerous in well-drained rabbit-grazed grassland, but also found in many other open habitats. There is one generation, from May to early August. It over-winters as a pupa. The main larval foodplant is Common Ragwort. Both leaves and flowers are eaten. Other ragworts and groundsels are sometimes used. It is easily disturbed during the day, and flies in sunshine.
