Callophrys gryneus, the juniper hairstreak or olive hairstreak, is a butterfly native to North America. It belongs in the family Lycaenidae. The juniper hairstreak has many subspecies or races, some of which may even be separate species. The upper side of the "olive" juniper hairstreak (C. g. gryneus) is tawny orange or a bronzy color in males, and blackish brown in females. The underside of the wings is bright green with a variable amount of brown scaling. There are two white postbasal spots and a white zigzag postmedian line edged inward with brown on the hindwing.
"Sweadner's" juniper hairstreak (C. g. sweadneri) is very similar to the gryneus race except the two white postbasal spots are reduced. The "Siva" juniper hairstreak (C. g. siva) is also similar to the gryneus race. It lacks the postbasal spots, the postmedian line is straight, and some individuals are brown. Intermediates of the gryneus and siva races occur in west Texas and New Mexico.
The underside of "Nelson's" juniper hairstreak (C. g. nelsoni) is brown with a violet sheen; the white postmedian line is faint, sometimes partial or absent; and the postbasal spots are lacking. "Muir's" juniper hairstreak... Wikipedia →
