Rare
Under 5% of wildlife watchers report an Arcastes biplagiata sighting in Singapore on a given day, based on 34 verified sightings from GBIF citizen-science data. It is the 432nd 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.
January
In that month about 10% of wildlife watchers report an Arcastes biplagiata in Singapore on a given day, against under 5% in February to December, the lowest months.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Arcastes biplagiata sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Chrysomelidae
The closest relatives of the Arcastes biplagiata 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 Arcastes biplagiata is recorded against all the insects logged in Singapore (34 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.
