Rare
Under 5% of wildlife watchers report a F-Winged Barklouse sighting in Tokyo on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 817th most-seen of the 1013 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.
January
In that month about 10% of wildlife watchers report a F-Winged Barklouse in Tokyo on a given day, against under 5% in February to December, the lowest months. That is one of Tokyo's driest months, with about 80 mm of rain against 250 mm in October.
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.
30th of 32
Of the 32 cities where we can rate F-Winged Barklouse sightings, Tokyo ranks 30th 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 Tokyo (7 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.
