The Xerces blue is a recently extinct species of butterfly in the gossamer-winged butterfly family, Lycaenidae. The species lived in coastal sand dunes of the Sunset District of the San Francisco Peninsula in California. The Xerces blue is believed to be the first American butterfly species to become extinct as a result of loss of habitat caused by urban development. The last Xerces blue was seen in 1941 or 1943 on land that is now part of the Golden Gate National Recreation Area.
Lycaenidae is the second-largest family of butterflies, with over 6,000 species worldwide, whose members are also called gossamer-winged butterflies. They constitute about 30% of the known butterfly species.
The Gila trout is a species of salmonid, related to the rainbow trout, native to the Southwest United States. Prior to 2006 the Gila trout was federally listed as endangered. In July 2006, after much work by the Game and Fish departments in New Mexico and Arizona, the US Forest Service and the US Fish and Wildlife Service, the Gila trout was down-listed to threatened, with a special provision called a "4d rule" that will allow limited sport fishing – for the first time in nearly half a century. By the time the Gila trout was closed to fishing in the 1950s, its numbers and range were so depleted and so reduced this copper-colored trout simply wasn't very accessible to anglers. As of 2011 there is fishing in both states for this fish.
The salt-marsh harvest mouse, also known as the red-bellied harvest mouse, is an endangered rodent endemic to the San Francisco Bay Area salt marshes in California.
The large copper is a butterfly of the family Lycaenidae. L. dispar has been commonly arranged into three subspecies: L. dispar dispar, (single-brooded) which was commonly found in England, but is now extinct, L. d. batavus, (single-brooded) can be found in the Netherlands and has been reintroduced into the United Kingdom, and lastly, L. d. rutilus, (double-brooded) which is widespread across central and southern Europe. The latter has been declining in many European countries, due to habitat loss. Currently L. dispar is in severe decline in northwest Europe, but expanding in central and northern Europe.

Lycaena epixanthe, also known as the bog copper or cranberry-bog copper, is a North American species of butterfly in the family Lycaenidae. Adults like to sip drops of dew clinging to leaves and almost exclusively nectar on their host plant, cranberries. Because of this, bog coppers will spend their entire lives within the area of a single acid bog. Even though their flight is weak and close to the ground, bog coppers are hard to catch because of the habitat in which they live. Also, 85% of the bog coppers life span is spent in the egg. It is listed as a species of special concern in the US state of Connecticut.
Lycaena orus, the western sorrel copper, is a butterfly of the family Lycaenidae. It is found only in South Africa. The habitat consists of fynbos at various altitudes, from sea level to montane regions.
Lycaena clarki, the eastern sorrel copper, is a butterfly of the family Lycaenidae. It is found only in South Africa.
Lycaena arota, the tailed copper, is a butterfly of the family Lycaenidae. It is found in North America from New Mexico north and west to Oregon, south to southern California and Baja California, Mexico.
Lycaena rubidus, the ruddy copper, is a butterfly of the family Lycaenidae. It is found in the western mountains of North America. Adults lay their eggs on plants of the genus Rumex, which later become the larval food plants. This butterfly gets its name from the brightly colored wings of the males, which are important in sexual selection. Its larvae exhibit mutualism with red ants, and are often raised in ant nests until they reach adulthood. Adults are on wing from mid-July to early August.
The blue copper, also known as Lycaena heteronea, is an American butterfly that belongs to the gossamer-winged family. The butterfly is named so because of the bright blue hue of the upper side of the males' wings. Females are brown on their upper side. Both sexes are white with black spots on the underside of the wings. Blue coppers are seen on the west coast of the United States and the southwest region of Canada, particularly British Columbia and Alberta. The males are often confused with Boisduval’s blue, another species of butterfly. Blue coppers prefer to live in areas where species of Eriogonum are found. Blue copper larvae sometimes form mutualistic associations with Formica francoeuri, an ant species.
Lycaena boldenarum, the boulder copper, is a species of butterfly which is endemic to New Zealand, it is found on both North Island and South Island in a wide variety of open habitats including grassland, shingle and sand dunes. They are normally only active in bright sunny conditions and their flight is usually low to the ground. The boldenarum part of the species name given by the Scottish entomologist Adam White in honour of his first wife, Helen and her sister Frances, whose maiden name was Bolden.
