Rare
Under 5% of wildlife watchers report a Dotted Blue sighting in Yellowstone National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 127th most-seen of the 160 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.
June and July
In those months about 10% of wildlife watchers report a Dotted Blue in Yellowstone National Park on a given day, against under 5% in August to May, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Dotted Blue sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
5th of 5
Of the 5 parks where we can rate Dotted Blue sightings, Yellowstone National Park ranks 5th at under 5%. The best odds are in Rocky Mountain National Park (United States, about 10%), Grand Teton National Park (United States, about 10%) and Joshua Tree National Park (United States, about 10%).
Same family: Lycaenidae

GBIF citizen-science records
It is estimated from how often the Dotted Blue is recorded against all the insects logged in Yellowstone National Park (5 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.
