Coenonympha tullia (Large Heath)  

The main foodplant of the larvae of the large heath is hare's-tail cottongrass (Eriophorum vaginatum) or occasionally common cottongrass (Eriophorum angustifolium) and the adult butterflies are, therefore, found on wet grassland or moorland. The distribution of the large heath is restricted to wet boggy habitats in northern Britain, Ireland, and a few isolated sites in Wales and central England. It is, however, widely distributed throughout the Outer Hebrides.
