Rare
Under 5% of wildlife watchers report an Ocean Spray Fairy Moth sighting in Olympic National Park on a given day, based on 7 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.
May and June
In those months about 10% of wildlife watchers report an Ocean Spray Fairy Moth in Olympic National Park on a given day, against under 5% in July to April, the lowest months. Those are among Olympic National Park's driest months, with about 90 mm of rain a month against 370 mm in November.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Ocean Spray Fairy Moth sightings with a recorded time, and about 7 in 10 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 Ocean Spray Fairy Moth sightings: under 5% of wildlife watchers there report one on a given day.
Same order: Lepidoptera
The closest relatives of the Ocean Spray Fairy Moth that you can see in Olympic National Park (order Lepidoptera, Butterflies and Moths) are Snowberry Checkerspot (about 20%), Pearl Crescent (about 20%) and Hydaspe Fritillary (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Ocean Spray Fairy Moth is recorded against all the insects logged in Olympic National Park (7 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.
