With luck
About 10% of wildlife watchers report a Paraglenea fortunei sighting in Tokyo on a given day, based on 212 verified sightings from GBIF citizen-science data. It is the 92nd most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Paraglenea fortunei in Tokyo on a given day, against under 5% in August to April, the lowest months.
Among the best
Of the 3 cities where we can rate Paraglenea fortunei sightings, Tokyo ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Nagoya (Japan, about 10%).
Same family: Cerambycidae
The closest relatives of the Paraglenea fortunei that you can see in Tokyo (family Cerambycidae, Longhorn Beetles) are Citrus Longhorn Beetle (about 10%), Aeolesthes chrysothrix (about 10%) and Yellow-Spotted Longicorn Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Paraglenea fortunei is recorded against all the insects logged in Tokyo (212 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.
