This species has a range of food plants including Lettuce (Lactuca sativa), Plantain (Plantago sp.)and Fat Hen (Chenopdium album) and is found throughout the UK?

The species emerges from May to August, surviving the winter in a protective cocoon within the soil, before pupating in the spring, there are two generations a year. The species has a wingspan of 35-44mm and is light brown to chestnut brown in colour, and on each forewing there is a large black edged kidney shape, a black edged circle about half the size of the kidney and next to the circle a solid black thin triangular marking (a dart), points towards the end of the wings.
