With luck
About 10% of wildlife watchers report a Pale-Banded Crescent sighting in Calakmul Biosphere Reserve on a given day, based on 9 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 31st most-seen of the 75 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Pale-Banded Crescent sightings with a recorded time, and nearly all 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 Pale-Banded Crescent is recorded against all the insects logged in Calakmul Biosphere Reserve (9 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.
