Rare
Under 5% of wildlife watchers report a Condylostylus longicornis sighting in San Francisco on a given day, based on 64 verified sightings from GBIF citizen-science data. It is the 200th 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 Condylostylus longicornis 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 Condylostylus longicornis sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
17th of 17
Of the 17 cities where we can rate Condylostylus longicornis sightings, San Francisco ranks 17th at under 5%. The best odds are in Cairo (Egypt, about 20%), Tel Aviv (Israel, about 10%) and Torreón (México, about 10%).
GBIF citizen-science records
It is estimated from how often the Condylostylus longicornis is recorded against all the insects logged in San Francisco (64 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.
