Rare
Under 5% of wildlife watchers report a Great Imperial sighting in Singapore on a given day, based on 50 verified sightings from GBIF citizen-science data. It is the 377th 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 30%, if each day is a fresh chance.
January and May–June
In those months about 10% of wildlife watchers report a Great Imperial in Singapore on a given day, against under 5% in February–April and July–December, the lowest months.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Great Imperial sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Lycaenidae
The closest relatives of the Great Imperial that you can see in Singapore (family Lycaenidae, Gossamer-winged Butterflies) are Branded Imperial (about 20%), Lesser Grass Blue (about 20%) and Tiny Grass Blue (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Great Imperial is recorded against all the insects logged in Singapore (50 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.
