Likely
About 40% of wildlife watchers report a Blue Monarch sighting in Arrecifes de Cozumel National Park on a given day, based on 48 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 2nd most-seen of the 27 insects we can rate there. Over three days the chance rises to about 70%, and over a week to over 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Blue Monarch is recorded against all the insects logged in Arrecifes de Cozumel National Park (48 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.
