Rare
Under 5% of wildlife watchers report a Thlaspida biramosa sighting in Tokyo on a given day, based on 53 verified sightings from GBIF citizen-science data. It is the 232nd 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 30%, if each day is a fresh chance.
April to July
In those months about 10% of wildlife watchers report a Thlaspida biramosa in Tokyo on a given day, against under 5% in August to March, the lowest months.
2nd of 3
Of the 3 cities where we can rate Thlaspida biramosa sightings, Tokyo ranks 2nd at under 5%. The best odds are in Taipei (Taiwan, about 10%).

GBIF citizen-science records
It is estimated from how often the Thlaspida biramosa is recorded against all the insects logged in Tokyo (53 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.
