With luck
About 10% of wildlife watchers report a Red-Washed Satyr sighting in Corcovado National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 116 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
October
In that month about 30% of wildlife watchers report a Red-Washed Satyr in Corcovado National Park on a given day, against under 5% in March, May–June and August–September, the lowest months. That is one of Corcovado National Park's wettest months, with about 770 mm of rain against 65 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Red-Washed Satyr sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
9th of 13
Of the 13 parks where we can rate Red-Washed Satyr sightings, Corcovado National Park ranks 9th at about 10%. The best odds are in Braulio Carrillo National Park (Costa Rica, about 30%), Gandoca-Manzanillo Wildlife Refuge (Costa Rica, about 30%) and Tenorio Volcano National Park (Costa Rica, about 20%).
GBIF citizen-science records
It is estimated from how often the Red-Washed Satyr is recorded against all the insects logged in Corcovado 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.
