Rare
Under 5% of wildlife watchers report a Diarsia canescens 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.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Diarsia canescens in Tokyo on a given day, so our monthly data shows no clear season.

Of the 3 cities where we can rate Diarsia canescens sightings, Tokyo ranks 3rd at under 5%. The best odds are in Nagoya (Japan, about 10%) and Seoul (South Korea, under 5%).
GBIF citizen-science records
It is estimated from how often the Diarsia canescens 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.
