Common in a wide range of habitats, including gardens, woodland, sand-dunes, moorland and fens throughout the British Isles, more commonly recorded at sugar than at light and recent apparent declines may reflect this, a species of conservation concern under the UK Biodiversity Action Plan. Widespread and still moderately common in Hampshire and on the Isle of Wight. Wingspan 32-40 mm. There are usually three small dots on the forewing, and the moth is likened to a mouse in coloration and in the way it scampers into cover when exposed. Larva feeds on a wide range of herbaceous plants and shrubs, over-wintering as an egg.
