Rare
Under 5% of wildlife watchers report a California Tortoiseshell sighting in Los Angeles on a given day, based on 16 verified sightings from GBIF citizen-science data.

Any time of year
In every month with enough records, under 5% of wildlife watchers report a California Tortoiseshell in Los Angeles on a given day, so our monthly data shows no clear season.

GBIF citizen-science records
It is estimated from how often the California Tortoiseshell is recorded against all the insects logged in Los Angeles (16 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.
