With luck
About 10% of wildlife watchers report a Mango Longhorn Beetle sighting in Taichung on a given day, based on 6 verified sightings from GBIF citizen-science data. It is the 155th most-seen of the 197 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
May to August

GBIF citizen-science records
It is estimated from how often the Mango Longhorn Beetle is recorded against all the insects logged in Taichung (6 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.
