Endangered (proposed as a future Red Data Book species) in sand-dunes and on limestone pavements in parts of western Ireland, northern Wales and the Isle of Man, predominantly coastal, a priority species under the UK Biodiversity Action Plan. Not recorded in Hampshire or on the Isle of Wight to date. Wingspan 14-18 mm. Somewhat variable in the brightness and contrast of the markings, but unlikely to be confused with any other British Pyrausta [Goater]. Larva feeds on Wild Thyme.
