The gatekeeper is orange with two large brown spots on its wings and a brown pattern on the edge of its wings.
The eyespots on the fore wings most likely reduce bird attacks, therefore the gatekeeper is often seen resting with its wings open.
A large number of aberrant forms are known, such as excessa, where specimens have two to four extra spots on the fore wing upperside.
The number of spots on the hind wing underside also varies.
