With luck
About 10% of wildlife watchers report a Purple Cerulean sighting in Brisbane on a given day, based on 76 verified sightings from GBIF citizen-science data. It is the 234th most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
January–April, June and October
In those months about 10% of wildlife watchers report a Purple Cerulean in Brisbane on a given day, against under 5% in May, July–September and November–December, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Purple Cerulean sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Purple Cerulean sightings: about 10% of wildlife watchers there report one on a given day.
Same family: Lycaenidae
The closest relatives of the Purple Cerulean that you can see in Brisbane (family Lycaenidae, Gossamer-winged Butterflies) are Rounded Sixline Blue (about 20%), Speckled Line-Blue (about 20%) and Lesser Grass Blue (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Purple Cerulean is recorded against all the insects logged in Brisbane (76 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.
