Rare
Under 5% of wildlife watchers report a Little Shaded Lichen Moth sighting in Seattle on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 306th 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.
July
In that month about 10% of wildlife watchers report a Little Shaded Lichen Moth in Seattle on a given day, against under 5% in August to June, the lowest months. That is one of Seattle's driest months, with about 20 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 Little Shaded Lichen Moth sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Little Shaded Lichen Moth that you can see in Seattle (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Isabella Tiger Moth (about 10%), Silver-Spotted Tiger Moth (about 10%) and Cinnabar Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Little Shaded Lichen Moth is recorded against all the insects logged in Seattle (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.
