Rare
Under 5% of wildlife watchers report a Lead-Colored Lichen Moth sighting in Washington on a given day, based on 8 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Lead-Colored Lichen Moth in Washington on a given day, so our monthly data shows no clear season.
Only Washington, in our data
Washington is the only city on Wallace's Line with enough records to rate Lead-Colored Lichen Moth sightings: under 5% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Lead-Colored Lichen Moth is recorded against all the insects logged in Washington (8 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.
