Rare
Under 5% of wildlife watchers report a Fog-Belt Bumble Bee 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 150th 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.
August
In that month about 10% of wildlife watchers report a Fog-Belt Bumble Bee in Olympic National Park on a given day, against under 5% in September to July, the lowest months. That is one of Olympic National Park's driest months, with about 45 mm of rain against 370 mm in November.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Fog-Belt Bumble Bee sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Olympic National Park, in our data
Olympic National Park is the only park on Wallace's Line with enough records to rate Fog-Belt Bumble Bee sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Bombus

GBIF citizen-science records
It is estimated from how often the Fog-Belt Bumble Bee 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.
