Rare
Under 5% of wildlife watchers report a Swamp Darter sighting in Brisbane on a given day, based on 51 verified sightings from GBIF citizen-science data. It is the 352nd most-seen of the 1083 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.
February to April
In those months about 10% of wildlife watchers report a Swamp Darter in Brisbane on a given day, against under 5% in May to January, the lowest months.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Swamp Darter sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Hesperiidae
The closest relatives of the Swamp Darter that you can see in Brisbane (family Hesperiidae, Skippers) are Wide-Brand Grass-Dart (about 30%), Splendid Ochre (about 20%) and Orange Palm Dart (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Swamp Darter is recorded against all the insects logged in Brisbane (51 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.
