With luck
About 10% of wildlife watchers report a Blue Monarch sighting in Manuel Antonio National Park on a given day, based on 11 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 32nd most-seen of the 69 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
May and July
In those months about 20% of wildlife watchers report a Blue Monarch in Manuel Antonio National Park on a given day, against under 5% in March–April and August–October, the lowest months. Those are among Manuel Antonio National Park's wettest months, with about 640 mm of rain a month against 35 mm in February.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Blue Monarch sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.

GBIF citizen-science records
It is estimated from how often the Blue Monarch is recorded against all the insects logged in Manuel Antonio National Park (11 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.
