Rare
Under 5% of wildlife watchers report a Physocephala burgessi sighting in San Francisco on a given day, based on 50 verified sightings from GBIF citizen-science data. It is the 263rd 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.
June
In that month about 10% of wildlife watchers report a Physocephala burgessi in San Francisco on a given day, against under 5% in July to May, the lowest months. That is one of San Francisco's driest months, with almost no rain against 110 mm in December.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Physocephala burgessi sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Physocephala burgessi sightings, San Francisco ranks 3rd at under 5%, level with the leaders once rounded. The best odds are in Seattle (United States, under 5%) and Portland (United States, under 5%).
GBIF citizen-science records
It is estimated from how often the Physocephala burgessi is recorded against all the insects logged in San Francisco (50 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.
