Rare
Under 5% of wildlife watchers report a Donacia provostii sighting in Beijing on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 247th most-seen of the 401 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.
June to August
In those months about 10% of wildlife watchers report a Donacia provostii in Beijing on a given day, against under 5% in September to May, the lowest months. Those are among Beijing's wettest months, with about 110 mm of rain a month against almost none in January.
Only Beijing, in our data
Beijing is the only city on Wallace's Line with enough records to rate Donacia provostii sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Chrysomelidae
The closest relatives of the Donacia provostii that you can see in Beijing (family Chrysomelidae, Leaf Beetles) are Chrysochus chinensis (about 10%), Oides decempunctata (about 10%) and Small Tortoise Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Donacia provostii is recorded against all the insects logged in Beijing (10 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.
