Rare
Under 5% of wildlife watchers report an Eresia aveyrona sighting in Great Bear Rainforest on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 200th most-seen of the 235 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, July and September
In those months about 10% of wildlife watchers report an Eresia aveyrona in Great Bear Rainforest on a given day, against under 5% in June, August and October–April, the lowest months.
Between 11 am and 2 pm
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.
5th of 5
Of the 5 parks where we can rate Eresia aveyrona sightings, Great Bear Rainforest ranks 5th at under 5%. The best odds are in Redwood National Park (United States, about 20%), Sequoia and Kings Canyon National Parks (United States, about 10%) and Yosemite National Park (United States, about 10%).
Same family: Nymphalidae
The closest relatives of the Eresia aveyrona that you can see in Great Bear Rainforest (family Nymphalidae, Brush-footed Butterflies) are Lorquin's Admiral (about 10%), Mourning Cloak (about 10%) and Milbert's Tortoiseshell (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Eresia aveyrona is recorded against all the insects logged in Great Bear Rainforest (5 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.
