Rare
Under 5% of wildlife watchers report a Pterolophia annulata sighting in Tokyo on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 482nd 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.
December
In that month about 10% of wildlife watchers report a Pterolophia annulata in Tokyo on a given day, against under 5% in January to November, the lowest months. That is one of Tokyo's driest months, with about 85 mm of rain against 250 mm in October.
3rd of 3
Of the 3 cities where we can rate Pterolophia annulata sightings, Tokyo ranks 3rd at under 5%. The best odds are in Tuen Mun (China, about 10%) and Osaka (Japan, under 5%).
GBIF citizen-science records
It is estimated from how often the Pterolophia annulata is recorded against all the insects logged in Tokyo (17 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.
