Rare
Under 5% of wildlife watchers report a Chalcophora japonica sighting in Hong Kong on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 1005th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Chalcophora japonica in Hong Kong on a given day, so our monthly data shows no clear season.
5th of 5
Of the 5 cities where we can rate Chalcophora japonica sightings, Hong Kong ranks 5th at under 5%. The best odds are in Guiyang (China, about 30%), Xiamen City (China, about 20%) and Osaka (Japan, under 5%).
Same order: Coleoptera
The closest relatives of the Chalcophora japonica that you can see in Hong Kong (order Coleoptera, Beetles) are Tricondyla pulchripes (about 20%), Six-Spotted Zigzag Ladybird (about 20%) and Cicindela juxtata (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Chalcophora japonica is recorded against all the insects logged in Hong Kong (5 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.
