Found in damp grassland, parkland, woodland and gardens.
Overwinters as a small larva. The adults come readily to light, sometimes in large numbers.
Note This is a very variable species and can be confused with Beaded Chestnut but in that species the orbicular and kidney marks are rather elongate or "squashed". If in doubt check for a dark fuzzy crescent moon on the upperside of the hindwing.
