Under 5% of wildlife watchers report a Yellow-Necked Caterpillar Moth sighting in Washington on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 1330th most-seen of the 1807 insects we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Yellow-Necked Caterpillar Moth is recorded against all the insects logged in Washington (9 verified sightings), 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.
