Rare
Under 5% of wildlife watchers report a Varied Sedge-Skipper sighting in Melbourne on a given day, based on 33 verified sightings from GBIF citizen-science data. It is the 323rd most-seen of the 875 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.
November and December
In those months about 10% of wildlife watchers report a Varied Sedge-Skipper in Melbourne on a given day, against under 5% in January to October, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Varied Sedge-Skipper 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 Melbourne, in our data
Melbourne is the only city on Wallace's Line with enough records to rate Varied Sedge-Skipper sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Hesperiidae
The closest relatives of the Varied Sedge-Skipper that you can see in Melbourne (family Hesperiidae, Skippers) are Yellow-Banded Dart (about 30%), Orange Palm Dart (about 10%) and Splendid Ochre (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Varied Sedge-Skipper is recorded against all the insects logged in Melbourne (33 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.
