Rare
Under 5% of wildlife watchers report a Ring-Legged Earwig sighting in San Francisco on a given day, based on 67 verified sightings from GBIF citizen-science data. It is the 194th 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 Ring-Legged Earwig in San Francisco on a given day, so our monthly data shows no clear season.
Between 6 and 9 am
Across all the parks we cover, that three-hour window holds the most Ring-Legged Earwig sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
20th of 24
Of the 24 cities where we can rate Ring-Legged Earwig sightings, San Francisco ranks 20th at under 5%. The best odds are in Mendoza (Argentina, about 20%), Buenos Aires (Argentina, about 10%) and Athens (Greece, about 10%).
GBIF citizen-science records
It is estimated from how often the Ring-Legged Earwig is recorded against all the insects logged in San Francisco (67 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.
