Rare
Under 5% of wildlife watchers report a California Tiger Moth sighting in San Francisco on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 622nd 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
In every month with enough records, under 5% of wildlife watchers report a California Tiger Moth in San Francisco on a given day, so our monthly data shows no clear season.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most California Tiger Moth sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only San Francisco, in our data
San Francisco is the only city on Wallace's Line with enough records to rate California Tiger Moth sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the California Tiger Moth that you can see in San Francisco (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Spotted Tussock Moth (about 10%) and Western Tussock Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the California Tiger Moth is recorded against all the insects logged in San Francisco (6 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.
