Rare
Under 5% of wildlife watchers report a Black-Spotted Blue Longicorn sighting in Tokyo on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 470th 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.
July
In that month about 10% of wildlife watchers report a Black-Spotted Blue Longicorn in Tokyo on a given day, against under 5% in August to June, the lowest months.
Only Tokyo, in our data

GBIF citizen-science records
It is estimated from how often the Black-Spotted Blue Longicorn is recorded against all the insects logged in Tokyo (18 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.
