With luck
About 10% of wildlife watchers report a Blue Monarch sighting in Parque Natural Metropolitano on a given day, based on 23 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 114 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, 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 Parque Natural Metropolitano (23 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.
