With luck
About 10% of wildlife watchers report a Yellow-Spotted Longicorn Beetle sighting in Nagoya on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 96th most-seen of the 195 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Yellow-Spotted Longicorn Beetle in Nagoya on a given day, against under 5% in November to May, the lowest months. That is one of Nagoya's wettest months, with about 220 mm of rain against 75 mm in January.

GBIF citizen-science records
It is estimated from how often the Yellow-Spotted Longicorn Beetle is recorded against all the insects logged in Nagoya (11 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.
