Rare
Under 5% of wildlife watchers report a Cotton Stem Moth sighting in Seattle on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 253rd 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Cotton Stem Moth in Seattle on a given day, so our monthly data shows no clear season.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Cotton Stem Moth sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Among the best
Of the 6 cities where we can rate Cotton Stem Moth sightings, Seattle ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Portland (United States, under 5%) and San Diego (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Cotton Stem Moth is recorded against all the insects logged in Seattle (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.
