Rare
Under 5% of wildlife watchers report a Eudonia echo sighting in Seattle on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 275th most-seen of the 428 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.
August
In that month about 10% of wildlife watchers report a Eudonia echo in Seattle on a given day, against under 5% in September to July, the lowest months. That is one of Seattle's driest months, with about 30 mm of rain against 190 mm in November.
Only Seattle, in our data
Seattle is the only city on Wallace's Line with enough records to rate Eudonia echo sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Eudonia echo is recorded against all the insects logged in Seattle (10 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.
