Rare
Under 5% of wildlife watchers report a Xylena formosa sighting in Tokyo on a given day, based on 26 verified sightings from GBIF citizen-science data. It is the 381st 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.
November to March
In those months about 10% of wildlife watchers report a Xylena formosa in Tokyo on a given day, against under 5% in April to October, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Xylena formosa sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Tokyo, in our data
Tokyo is the only city on Wallace's Line with enough records to rate Xylena formosa sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Xylena formosa is recorded against all the insects logged in Tokyo (26 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.
