Rare
Under 5% of wildlife watchers report a California Tiger Moth 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 162nd 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.
April and June
In those months about 10% of wildlife watchers report a California Tiger Moth in Olympic National Park on a given day, against under 5% in May and July–March, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most California Tiger Moth 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 California Tiger Moth sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the California Tiger Moth that you can see in Olympic National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Spotted Tussock Moth (about 10%), Silver-Spotted Tiger Moth (about 10%) and Virginian Tiger Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the California Tiger Moth 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.
