With luck
About 10% of wildlife watchers report an Anomala expansa sighting in Taichung on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 172nd 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.
March and May–June
In those months about 10% of wildlife watchers report an Anomala expansa in Taichung on a given day, against under 5% in April and July–February, the lowest months. Those are among Taichung's wettest months, with about 220 mm of rain a month against 40 mm in December.
Among the best
Of the 3 cities where we can rate Anomala expansa sightings, Taichung ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Tainan (Taiwan, about 10%).
Same family: Scarabaeidae
The closest relatives of the Anomala expansa that you can see in Taichung (family Scarabaeidae, Scarabs) are Japanese Rhinoceros Beetle (about 20%), Oriental Flower Beetle (about 10%) and Macronota shangaicus (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Anomala expansa is recorded against all the insects logged in Taichung (5 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.
