Rare
Under 5% of wildlife watchers report a F-Winged Barklouse sighting in San Francisco on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 356th 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 F-Winged Barklouse in San Francisco on a given day, so our monthly data shows no clear season.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most F-Winged Barklouse sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
31st of 32
Of the 32 cities where we can rate F-Winged Barklouse sightings, San Francisco ranks 31st at under 5%. The best odds are in Berlin (Germany, about 10%), London (United Kingdom, about 10%) and Bucharest (Romania, about 10%).
GBIF citizen-science records
It is estimated from how often the F-Winged Barklouse is recorded against all the insects logged in San Francisco (19 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.
