Grayling

The grayling is one of our largest brown butterflies and a master of disguise - its cryptic colouring helps to camouflage it against bare earth and stones in its coastal habitats and on inland heathlands.

Ynghylch

A medium-sized butterfly, the grayling inhabits sunny places; adults spend much of their time sunbathing on the ground, with their wings closed and angled to catch the full rays of the sun. Found around the coast and on southern heathlands, adults are on the wing in the summer, from June to September. Cryptic colouring provides the grayling with excellent camouflage, so it can be hard to spot on stony ground. The caterpillars feed on a variety of grasses including sheep's fescue, red fescue and marram grass.

Sut i'w hadnabod

The grayling is mainly dark brown above, with washed-out orange markings. The underside of the forewing is orange and the hindwing has an intricate grey-and-black pattern. The best way to identify the 'brown' butterflies is by looking at the eyespots on their wings. The combination of orange and brown markings, together with two large eyespots on the underside of the forewing and one smaller eyespot on the hindwing, is unique to the grayling.
