With luck
About 10% of wildlife watchers report an Elongate White-Marmorated Longicorn Beetle sighting in Tokyo on a given day, based on 96 verified sightings from GBIF citizen-science data. It is the 157th 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 30%, if each day is a fresh chance.
June to August
In those months about 10% of wildlife watchers report an Elongate White-Marmorated Longicorn Beetle in Tokyo on a given day, against under 5% in September to May, the lowest months.

GBIF citizen-science records
It is estimated from how often the Elongate White-Marmorated Longicorn Beetle is recorded against all the insects logged in Tokyo (96 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.
