Possible
About 20% of wildlife watchers report a Japanese Drone Beetle sighting in Chengdu on a given day, based on 27 verified sightings from GBIF citizen-science data. It is the 8th most-seen of the 26 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.
June and July
In those months about 40% of wildlife watchers report a Japanese Drone Beetle in Chengdu on a given day, against under 5% in March–May and August–January, the lowest months. Those are among Chengdu's wettest months, with about 200 mm of rain a month against 10 mm in January.
Yes
Of the 9 cities where we can rate Japanese Drone Beetle sightings, Chengdu has the highest daily chance: about 20%. Next come Sendai (Japan, about 20%) and Nagoya (Japan, about 10%).
GBIF citizen-science records
It is estimated from how often the Japanese Drone Beetle is recorded against all the insects logged in Chengdu (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.
