With luck
About 10% of wildlife watchers report an Anna's Blue sighting in Olympic National Park on a given day, based on 34 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 72nd most-seen of the 207 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 to September
In those months about 10% of wildlife watchers report an Anna's Blue in Olympic National Park on a given day, against under 5% in October to June, the lowest months. Those are among Olympic National Park's driest months, with about 70 mm of rain a month against 370 mm in November.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Anna's Blue sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 3 parks where we can rate Anna's Blue sightings, Olympic National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Sequoia and Kings Canyon National Parks (United States, about 10%).
Same family: Lycaenidae
The closest relatives of the Anna's Blue that you can see in Olympic National Park (family Lycaenidae, Gossamer-winged Butterflies) are Boisduval's Blue (about 10%), Purplish Copper (about 10%) and Arctic Blue (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Anna's Blue is recorded against all the insects logged in Olympic National Park (34 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.
