Goniaea australasiae
In 3 days ~50% in a week ~80%
Goniaea australasiae is a species of grasshopper in the family Acrididae. Experiments have been carried out with G. australasiae to study the time of genetic recombination in relation to the sequence of stages in meiosis, the relationship of chiasmata to crossing over, and the mechanism of recombination. Combined cytological and autoradiographic analyses of meiosis showed that crossing over is achieved by breakage and exchange of segments of nonsister, homologous chromatids, and each such exchange event results in the formation of a cytologically visible chiasma. The meiotic stage at which this form of recombination takes place has been identified as "early pachytene," and it is well removed from premeiotic chromosome duplication. Wikipedia →

Possible
About 20% of wildlife watchers report a Common Gumleaf Grasshopper sighting in Flinders Ranges National Park on a given day, based on 8 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 17th most-seen of the 25 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
October
In that month about 40% of wildlife watchers report a Common Gumleaf Grasshopper in Flinders Ranges National Park on a given day, against under 5% in December to July, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Common Gumleaf Grasshopper sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 7 parks where we can rate Common Gumleaf Grasshopper sightings, Flinders Ranges National Park has the highest daily chance: about 20%. Next come Freycinet National Park (Australia, about 10%) and Wilsons Promontory National Park (Australia, about 10%).
Same family: Acrididae
The closest relatives of the Common Gumleaf Grasshopper that you can see in Flinders Ranges National Park (family Acrididae, Short-horned Grasshoppers) are Australian Plague Locust (about 30%), Bark-Mimicking Grasshopper (about 20%) and Common Urnisa (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Gumleaf Grasshopper is recorded against all the insects logged in Flinders Ranges National Park (8 verified sightings from 2019 to 2026), 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.
