With luck
About 10% of wildlife watchers report a Caio championi sighting in Arenal Volcano National Park on a given day, based on 10 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 129th most-seen of the 302 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Caio championi is recorded against all the insects logged in Arenal Volcano National Park (10 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.
