Part of the family Lycaenidae, Callophrys--or green hairstreak butterflies--are common in North America. Species showing green camouflage include the coastal green hairstreak (C. dumetorum), which is found in coastal California, often near wild buckwheat plants; the Western green hairstreak (C. affinis), with green wing undersides; and the Sheridan's green hairstreak (C. sheridanii), showing bright-green to dark gray-green wing undersides, sometimes with white markings. The green hairstreak (C. rubi), which is widespread in Europe, rests with wings closed, thus showing the green undersides.
Cyanophrys is another genus of Lycaenidae butterflies, also called greenstreaks. Some of them show green wing undersides, which help them to camouflage when resting on leaves. The tropical greenstreak (C. herodotus) ranges from north Brazil through Central and South America to Mexico, has blue upper sides, green undersides and face.
The green skipper, or Hesperia viridis, is a butterfly found in North America, often near grasses such as the blue grama, fluff grass and buffalograss. The green skipper has bright green-orange wings, with white spots. Other species showing green camouflage within this genus are the Western branded skipper (H. colorado) and the common branded skipper (H. comma). The Brimstone butterfly (Gonepteryx rhamni) is widespread in Europe, extending as far as North Africa and Mongolia. This species has yellow-green, leaf-shaped wings.
Euchloe is part of the family Piridae, often called marbles or dappled whites. Species showing green camouflage include the green-striped white (E. belemia), found in northern Africa, southern Spain and Portugal; the Eastern greenish black-tip (E. penia), which is predominantly green, with yellow marks on the undersides and black marks on the upper sides; and the North American green marble (E. naina) and large marble (E. ausonides), which are similar to the green-striped white.
