SATYR BUTTERFLY

also called Brown, any of certain species of butterflies belonging to the family Satyridae (order Lepidoptera), abundant during summer months in the woods and grasslands of the United States and Europe. The adults are dull brown or grey, while the larvae possess small, forked tail-like appendages on their abdomens. Adult butterflies have brown wings with a span of five to six centimetres and conspicuous circular markings on them. These false eyes on the wings may serve to frighten or distract predatory birds.
