Rare
Under 5% of wildlife watchers report a Sumitrosis rosea sighting in Washington on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 1256th 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 Sumitrosis rosea 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 Sumitrosis rosea sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Sumitrosis rosea is recorded against all the insects logged in Washington (9 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.
