It is the 679th 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 Silver-Tailed Petalcutter 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.
