Under 5% of wildlife watchers report a Black Drone Beetle sighting in Tokyo on a given day, based on 41 verified sightings from GBIF citizen-science data. It is the 279th most-seen of the 1013 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.
July to September
In those months about 10% of wildlife watchers report a Black Drone Beetle in Tokyo on a given day, against under 5% in October to June, the lowest months.
Only Tokyo, in our data
Tokyo is the only city on Wallace's Line with enough records to rate Black Drone Beetle sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Scarabaeidae
The closest relatives of the Black 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 Black Drone Beetle is recorded against all the insects logged in Tokyo (41 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.
