With luck
About 10% of wildlife watchers report a Japanese Drone Beetle sighting in Tokyo on a given day, based on 273 verified sightings from GBIF citizen-science data. It is the 58th most-seen of the 1013 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
June and July
In those months about 20% of wildlife watchers report a Japanese Drone Beetle in Tokyo on a given day, against under 5% in September to May, the lowest months.
5th of 9
Of the 9 cities where we can rate Japanese Drone Beetle sightings, Tokyo ranks 5th at about 10%. The best odds are in Chengdu (China, about 20%), Sendai (Japan, about 20%) and Nagoya (Japan, about 10%).
Same family: Scarabaeidae
The closest relatives of the Japanese Drone Beetle that you can see in Tokyo (family Scarabaeidae, Scarabs) are Green Chafer (about 20%), Japanese Rhinoceros Beetle (about 10%) and Japanese Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Japanese Drone Beetle is recorded against all the insects logged in Tokyo (273 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.
