Dynastor darius, also known as the daring-owl butterfly, is a species of butterfly in the family Nymphalidae. The daring-owl butterfly is best known for its chrysalis's resemblance to a viper as a form of Batesian mimicry. It is native to Central and South America.
Dynastor darius is a large butterfly, with the costal edge of the forewings very curved. The upper side of the wings is dark black to brown in colour, with the forewings spotted with white in a short band from the middle of the costal edge and in isolated spots in the postdiscal area. The underside is beige with, on the forewing, a large whitish area along the costal edge from its middle to the apex. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Daring Owl-Butterfly is recorded against all the insects logged in Masaya Volcano National Park (12 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.
