With luck
About 10% of wildlife watchers report an Erichson's White-Skipper sighting in Saguaro National Park on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 75th most-seen of the 354 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Erichson's White-Skipper is recorded against all the insects logged in Saguaro National Park (30 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.
