Rare
Under 5% of wildlife watchers report a Donacia japana sighting in Singapore on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 788th most-seen of the 1045 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 Donacia japana in Singapore on a given day, so our monthly data shows no clear season.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Donacia japana sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Chrysomelidae
The closest relatives of the Donacia japana that you can see in Singapore (family Chrysomelidae, Leaf Beetles) are Baliosus pectoralis (about 10%), Gonophora pulchella (about 10%) and Sweetpotato Leaf Beetle (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Donacia japana is recorded against all the insects logged in Singapore (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.
