Rare
Under 5% of wildlife watchers report a Cyril's Brown sighting in Sydney on a given day, based on 36 verified sightings from GBIF citizen-science data. It is the 238th most-seen of the 742 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.
August and September
In those months about 10% of wildlife watchers report a Cyril's Brown in Sydney on a given day, against under 5% in October to July, the lowest months.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Cyril's Brown sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Sydney, in our data
Sydney is the only city on Wallace's Line with enough records to rate Cyril's Brown sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Nymphalidae
The closest relatives of the Cyril's Brown that you can see in Sydney (family Nymphalidae, Brush-footed Butterflies) are Australian Common Crow (about 20%), Meadow Argus (about 10%) and Australian Painted Lady (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cyril's Brown is recorded against all the insects logged in Sydney (36 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.
