Anomala albopilosa, known by the common names green chafer, white-haired leaf chafer and sugarcane white grub, is a species of chafer beetle in the family Scarabaeidae. It was originally described in the genus Euchlora by Frederick William Hope in 1839.

Possible
About 20% of wildlife watchers report a Green Chafer sighting in Tokyo on a given day, based on 775 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Green Chafer in Tokyo on a given day, against under 5% in November to May, the lowest months.
4th of 5
Of the 5 cities where we can rate Green Chafer sightings, Tokyo ranks 4th at about 20%. The best odds are in Nagoya (Japan, about 30%), Hiroshima (Japan, about 20%) and Osaka (Japan, about 20%).
GBIF citizen-science records
It is estimated from how often the Green Chafer is recorded against all the insects logged in Tokyo (775 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.
