It is the 480th most-seen of the 737 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

GBIF citizen-science records
It is estimated from how often the Bicolored Webspinner is recorded against all the insects logged in San Francisco (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.
