Rare
Under 5% of wildlife watchers report a Tissue Moth sighting in San Francisco on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 362nd most-seen of the 737 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Tissue Moth in San Francisco on a given day, so our monthly data shows no clear season.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Tissue Moth sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is seen both by day and at night.
4th of 4
Of the 4 cities where we can rate Tissue Moth sightings, San Francisco ranks 4th at under 5%. The best odds are in Seattle (United States, about 10%), Portland (United States, about 10%) and Vancouver (Canada, under 5%).
GBIF citizen-science records
It is estimated from how often the Tissue Moth is recorded against all the insects logged in San Francisco (18 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.
