With luck
About 10% of wildlife watchers report a California Black sighting in Olympic National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 98th 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 30%, if each day is a fresh chance.
April to July
In those months about 10% of wildlife watchers report a California Black in Olympic National Park on a given day, against under 5% in August to March, the lowest months. Those are among Olympic National Park's driest months, with about 100 mm of rain a month against 370 mm in November.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most California Black sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate California Black sightings, Olympic National Park ranks 2nd at about 10%. The best odds are in Redwood National Park (United States, about 20%).
GBIF citizen-science records
It is estimated from how often the California Black is recorded against all the insects logged in Olympic National Park (12 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.
