Rare
Under 5% of wildlife watchers report a Lettered Habrosyne Moth 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 113th 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 to August
In those months about 10% of wildlife watchers report a Lettered Habrosyne Moth in Olympic National Park on a given day, against under 5% in September to May, the lowest months. Those are among Olympic National Park's driest months, with about 55 mm of rain a month against 370 mm in November.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Lettered Habrosyne Moth sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
7th of 8
Of the 8 parks where we can rate Lettered Habrosyne Moth sightings, Olympic National Park ranks 7th at under 5%. The best odds are in Gros Morne National Park (Canada, about 10%), Jasper National Park (Canada, about 10%) and Pacific Rim National Park Reserve (Canada, about 10%).
Same order: Lepidoptera
The closest relatives of the Lettered Habrosyne 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 Lettered Habrosyne Moth 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.
