Nationally scarce (Nb) on moorland, rough grassland and upland woodland, generally restricted to uplands in parts of Scotland, Shetland and northern England, rare elsewhere, a priority species under the UK Biodiversity Action Plan. In Hampshire and on the Isle of Wight formerly resident in all three vice-counties, now an extremely scarce presumed immigrant: the only recent record is of one taken at sugar at Freshwater in October 1978. Wingspan 58-68 mm. There is sometimes a very dark median subdorsal patch which can cause confusion with Red Sword-grass X. vetusta. Larva feeds on Creeping Thistle, Musk Thistle, Spear Thistle, Creeping Cinquefoil, Common Restharrow, Groundsel, Dock and Hop.
