Callophrys henrici, the Henry's elfin or woodland elfin, is a North American butterfly in the family Lycaenidae. In Canada it is found from southern Manitoba to southern Nova Scotia. It has two main groups of populations in the United States; the first is found along the Atlantic Coast and uses various hollies (Ilex) as host plants; and the second is found mainly in the north and the Appalachians where they use redbud as a host plant. Henry's elfin is increasing in New England because of an introduced buckthorn it now uses as a host plant. It is listed as a species of special concern in the US state of Connecticut.
Callophrys irus, the frosted elfin, is a species of Lycaenidae that is native to North America.
Callophrys sheridanii, the Sheridan's hairstreak and Sheridan's green hairstreak, is a butterfly in the family Lycaenidae.

Callophrys augustinus, the brown elfin, is butterfly of the family Lycaenidae. It is found from Newfoundland north and west through the northern United States and the prairie provinces to Alaska. To the south it ranges in Appalachian Mountains to northern Georgia and northern Alabama, further south through the western mountains to northern Baja California in Mexico. Subspecies iroides is known as the western elfin.
Callophrys polios, the hoary elfin, is a butterfly of the family Lycaenidae. It has a very local distribution in the United States from Maine south to New Jersey and in the Appalachian Mountains to Virginia, west across the Great Lakes states and the southern prairie provinces and north to Alaska. Along the Pacific Coast it is found to northern California and in the Rocky Mountains south to northern New Mexico. It is listed as a species of special concern and believed extirpated in the US state of Connecticut.
Callophrys mossii, commonly known as Moss's elfin, stonecrop elfin or Schryver's elfin, is a species of butterfly native to North America in the family Lycaenidae. It is found from British Columbia south to southern California and east to Wyoming and Colorado in isolated populations. The habitat consists of rocky outcrops, woody canyons and cliffs.
Callophrys xami, commonly referred to as the xami hairstreak or green hairstreak, is a butterfly included in the subgenus Xamia and the genus Callophrys in the family Lycaenidae. It was described by Tryon Reakirt in 1867. Other common names for this species, depending on the region, include green hairstreak and elfin. C. xami is considered to be a very rare species of butterfly, and its typical range is in southern Arizona and Texas including down south to Guatemala. The juniper hairstreak and the silver-banded hairstreak butterflies are similar species, but both differ significantly from C. xami in regards to the postmedian white line running across the butterfly wings.
