Rare
Under 5% of wildlife watchers report a White-Striped Black sighting in Olympic National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 123rd most-seen of the 207 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 White-Striped Black in Olympic National Park on a given day, against under 5% in August to May, the lowest months. Those are among Olympic National Park's driest months, with about 60 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 White-Striped 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.
9th of 9
Of the 9 parks where we can rate White-Striped Black sightings, Olympic National Park ranks 9th at under 5%. The best odds are in Great Smoky Mountains National Park (United States, about 20%), Kluane National Park (Canada, about 20%) and Point Pelee National Park (Canada, about 10%).
GBIF citizen-science records
It is estimated from how often the White-Striped Black is recorded against all the insects logged in Olympic National Park (10 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.
