Under 5% of wildlife watchers report a Julia's Idia Moth sighting in Washington on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 1533rd 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.
Any time of year

GBIF citizen-science records
It is estimated from how often the Julia's Idia 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.
