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 →

With luck
About 10% of wildlife watchers report a Mitoura siva sighting in Grand Canyon National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 68th most-seen of the 143 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
July
In that month about 20% of wildlife watchers report a Mitoura siva in Grand Canyon National Park on a given day, against under 5% in September to April, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Mitoura siva sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Grand Canyon National Park, in our data

GBIF citizen-science records
It is estimated from how often the Mitoura siva is recorded against all the insects logged in Grand Canyon National Park (11 verified sightings from 2019 to 2026), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
