With luck
About 10% of wildlife watchers report a Japanese Drone Beetle sighting in Nanjing on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 112th most-seen of the 272 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 30% of wildlife watchers report a Japanese Drone Beetle in Nanjing on a given day, against under 5% in September to May, the lowest months. That is one of Nanjing's wettest months, with about 240 mm of rain against 40 mm in December.
7th of 9
Of the 9 cities where we can rate Japanese Drone Beetle sightings, Nanjing ranks 7th 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 Nanjing (family Scarabaeidae, Scarabs) are Japanese Rhinoceros Beetle (about 20%), Eophileurus chinensis (about 10%) and Oriental Flower 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 Nanjing (12 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.
