Possible
About 20% of wildlife watchers report a Blue Copper sighting in Glacier National Park on a given day, based on 58 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 26th most-seen of the 147 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
July and August
In those months about 20% of wildlife watchers report a Blue Copper in Glacier National Park on a given day, against under 5% in January–May and October–November, the lowest months. Those are among Glacier National Park's driest months, with about 30 mm of rain a month against 80 mm in February.
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.
Among the best
Of the 6 parks where we can rate Blue Copper sightings, Glacier National Park ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Grand Teton National Park (United States, about 20%).
Same genus: Tharsalea

GBIF citizen-science records
It is estimated from how often the Blue Copper is recorded against all the insects logged in Glacier National Park (58 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.
