Grayling; Sátiro común

Description:

Butterfly of the family Nymphalidae. 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 near its apex become visible. This butterfly, the largest of 'browns', is a master of disguise - although fairly conspicuous when in flight, it can mysteriously disappear as soon as it lands, perfectly camouflaged against a background of bare earth and stones, always resting with its wings closed. When it first lands, and when disturbed, the butterfly will raise its forewings for a second or so, revealing dark eye spots that stand out against a beautiful spectrum of browns. This butterfly also has a curious technique for regulating body temperature by leaning its wings at different angles to the sun. The larvae feed on various types of gramineae: Festuca ovina, Brachypodium pinnatum, Brachypodium sylvaticum, Arrhenatherum elatius, Festuca paniculada, Festuca ampla…

Habitat:

Spotted at the mountains close to a river. Parque Nacional de Sierra de Gredos.
