It is the 38th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.

GBIF citizen-science records
It is estimated from how often the Atrocalopteryx atrata is recorded against all the insects logged in Tokyo (400 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.
