Possible
About 20% of wildlife watchers report a Yellow-Banded Dart sighting in Sydney on a given day, based on 520 verified sightings from GBIF citizen-science data. It is the 16th most-seen of the 742 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
April
In that month about 30% of wildlife watchers report a Yellow-Banded Dart in Sydney on a given day, against under 5% in June to August, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Yellow-Banded Dart sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 cities where we can rate Yellow-Banded Dart sightings, Sydney ranks 2nd at about 20%. The best odds are in Melbourne (Australia, about 30%).
Same family: Hesperiidae
The closest relatives of the Yellow-Banded Dart that you can see in Sydney (family Hesperiidae, Skippers) are 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 Yellow-Banded Dart is recorded against all the insects logged in Sydney (520 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.
