Godyris zavaleta
In 3 days ~30% in a week ~60%
Godyris zavaleta, the Zavaleta glasswing, is a species of butterfly of the family Nymphalidae. It is found from Costa Rica to southern Peru. The habitat consists of lowland and mid-elevation rainforests at altitudes up to 900 meters.
Adults visit the flowers of Epidendrum panniculatum. Adult males sequester pyrrolizidine alkaloids from Heliotropium, Tournefourtia, Myosotis, Eupatorium, Neomiranda and Senecio species, making the species toxic to deter predation by birds.
The larvae feed on Solanum species (including S. brenesii), but have also been recorded feeding on Cestrum nocturnum. Wikipedia →

GBIF citizen-science records
It is estimated from how often the Zavaleta Glasswing is recorded against all the insects logged in Arenal Volcano National Park (28 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.
