Taractrocera ina, the ina grassdart or no-brand grass-dart, is a butterfly of the family Hesperiidae. It is found in northern, central and eastern Australia in scattered localities, south to western New South Wales and Papua New Guinea.
The wingspan is about 20 mm. The larvae feed on Cymbopogon citrata, Paspalum urvillei, Urochloa decumbens, Sorghum verticilliflorum, Paspalum conjugatum, Panicum maximum and Oryza sativa. It constructs a tubular shelter made of the leaves of its host plant. Wikipedia →

Rare
Under 5% of wildlife watchers report an Ina Grass-Dart sighting in Brisbane on a given day, based on 12 verified sightings from GBIF citizen-science data. It is the 636th 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 20%, if each day is a fresh chance.
February
In that month about 10% of wildlife watchers report an Ina Grass-Dart in Brisbane on a given day, against under 5% in March to January, the lowest months. That is one of Brisbane's wettest months, with about 160 mm of rain against 40 mm in July.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Ina Grass-Dart sightings with a recorded time, and nearly all 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 Ina Grass-Dart sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Hesperiidae
The closest relatives of the Ina Grass-Dart 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 Ina Grass-Dart is recorded against all the insects logged in Brisbane (12 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.
