Rare
Under 5% of wildlife watchers report a Western Fairy Lady Beetle sighting in Olympic National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 182nd 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 20%, if each day is a fresh chance.
June and September
In those months about 10% of wildlife watchers report a Western Fairy Lady Beetle in Olympic National Park on a given day, against under 5% in July–August and October–May, 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 11 pm and 2 am
Across all the parks we cover, that three-hour window holds the most Western Fairy Lady Beetle sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
Among the best
Of the 2 parks where we can rate Western Fairy Lady Beetle sightings, Olympic National Park ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Great Bear Rainforest (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Western Fairy Lady Beetle is recorded against all the insects logged in Olympic National Park (8 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.
