Rare
Under 5% of wildlife watchers report a Blue Copper sighting in Yosemite National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 174th most-seen of the 227 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
July to September
In those months about 10% of wildlife watchers report a Blue Copper in Yosemite National Park on a given day, against under 5% in October to June, the lowest months. Those are among Yosemite National Park's driest months, with about 25 mm of rain a month against 220 mm in January.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Blue Copper sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
6th of 6
Of the 6 parks where we can rate Blue Copper sightings, Yosemite National Park ranks 6th at under 5%. The best odds are in Grand Teton National Park (United States, about 20%), Glacier National Park (United States, about 20%) and Yellowstone National Park (United States, about 10%).
Same genus: Tharsalea
The closest relatives of the Blue Copper that you can see in Yosemite National Park (genus Tharsalea) are Edith's Copper (about 10%), Lilac-Bordered Copper (about 10%) and Mariposa Copper (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Blue Copper is recorded against all the insects logged in Yosemite National Park (6 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.
