The Grayling ("Hipparchia semele") is a species in the brush-footed butterfly family Nymphalidae. It sometimes occurs in coastal areas of northeast Scotland such as the Fowlsheugh Nature Reserve. It can also be found near the coast around England, such as Fire Beacon Hill. This species is often associated with bare ground and rocky hills.

They rest with closed wings, forewings lowered between the hindwings as do many Satyrinae. When disturbed, they raise the forewing so that the large eyespots bnear its apex become visible. A predator attacking the butterfly could either be startled by the sudden appearance of the pattern, or be enticed into attacking the conspicuous spot rather than the butterfly's body (Stevens, 2005). A very similar species has recently been in discovered at Faraulep, Stripe-backed Grayling.

It is now a UK BAP species (Butterfly Conservation, 2007).
