This is a relatively common butterfly that is unmistakable when seen at rest - the rings on the hindwings giving this butterfly its common name. The uppersides are a uniform chocolate brown that distinguish this butterfly from the closely-related Meadow Brown. Despite this uniformity, a newly-emerged adult is a surprisingly beautiful insect, the velvety wings providing a striking contrast with the delicate white fringes found on the wing edges. The dark colouring also allows this butterfly to quickly warm up - this butterfly being one of the few that flies on overcast days.
Variation in this butterfly is primarily focused on the rings on the hindwings, the lanceolata aberration being particularly striking, where the rings are elongated to form teardrops. Other aberrations occur where the rings are greatly reduced or completely absent.
