With luck
About 10% of wildlife watchers report a F-Winged Barklouse sighting in London on a given day, based on 115 verified sightings from GBIF citizen-science data. It is the 323rd most-seen of the 1504 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
November to January
In those months about 20% of wildlife watchers report a F-Winged Barklouse in London on a given day, against under 5% in June to September, the lowest months.
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.
Among the best
Of the 32 cities where we can rate F-Winged Barklouse sightings, London ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Berlin (Germany, about 10%).
GBIF citizen-science records
It is estimated from how often the F-Winged Barklouse is recorded against all the insects logged in London (115 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.
