Rare
Under 5% of wildlife watchers report a Red Spotted Longhorn Beetle sighting in Tokyo on a given day, based on 40 verified sightings from GBIF citizen-science data. It is the 284th 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.
May and June
In those months about 10% of wildlife watchers report a Red Spotted Longhorn Beetle in Tokyo on a given day, against under 5% in July to April, the lowest months.
Only Tokyo, in our data
Tokyo is the only city on Wallace's Line with enough records to rate Red Spotted Longhorn Beetle sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Cerambycidae
The closest relatives of the Red Spotted Longhorn Beetle that you can see in Tokyo (family Cerambycidae, Longhorn Beetles) are Citrus Longhorn Beetle (about 10%), Paraglenea fortunei (about 10%) and Aeolesthes chrysothrix (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red Spotted Longhorn Beetle is recorded against all the insects logged in Tokyo (40 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.
