About 30% of wildlife watchers report a Phaon Crescent sighting in Merritt Island National Wildlife Refuge on a given day, based on 118 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 189 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Phaon Crescent is recorded against all the insects logged in Merritt Island National Wildlife Refuge (118 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.
