Rare
Under 5% of wildlife watchers report a Eudonia rectilinea sighting in Portland on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 296th most-seen of the 507 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.

Of the 2 cities where we can rate Eudonia rectilinea sightings, Portland has the highest daily chance: under 5%. Next come Seattle (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Eudonia rectilinea is recorded against all the insects logged in Portland (14 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.
