Rare
Under 5% of wildlife watchers report an Anomala expansa sighting in Taipei on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 298th most-seen of the 765 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
May to August
In those months about 10% of wildlife watchers report an Anomala expansa in Taipei on a given day, against under 5% in September to April, the lowest months. Those are among Taipei's wettest months, with about 230 mm of rain a month against 90 mm in February.
3rd of 3
Of the 3 cities where we can rate Anomala expansa sightings, Taipei ranks 3rd at under 5%. The best odds are in Tainan (Taiwan, about 10%) and Taichung (Taiwan, about 10%).
Same family: Scarabaeidae
The closest relatives of the Anomala expansa that you can see in Taipei (family Scarabaeidae, Scarabs) are Japanese Rhinoceros Beetle (about 20%), Taiwanese Spurred Flower Beetle (about 10%) and Protaetia culta (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 Taipei (27 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.
