With luck
About 10% of wildlife watchers report an Eresia aveyrona sighting in Olympic National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 105th 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 July–August
In those months about 10% of wildlife watchers report an Eresia aveyrona in Olympic National Park on a given day, against under 5% in June and September–April, the lowest months. Those are among Olympic National Park's driest months, with about 60 mm of rain a month against 370 mm in November.

Across all the parks we cover, that three-hour window holds the most Eresia aveyrona sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5

GBIF citizen-science records
It is estimated from how often the Eresia aveyrona is recorded against all the insects logged in Olympic National Park (11 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.
