With luck
About 10% of wildlife watchers report a Yellow-Spotted Longicorn Beetle sighting in Taipei on a given day, based on 91 verified sightings from GBIF citizen-science data. It is the 127th most-seen of the 765 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.
January and May–November

GBIF citizen-science records
It is estimated from how often the Yellow-Spotted Longicorn Beetle is recorded against all the insects logged in Taipei (91 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.
