Gastrimargus musicus
In 3 days ~10% in a week ~20%
Gastrimargus musicus, the yellow-winged locust or yellow-winged grasshopper, is a common grasshopper in Australia. It only displays its yellow back wings in flight, when it also emits a loud clicking or crackling sound. When swarming, the adults become dark brown.
They are sometimes confused with the Australian plague locust (Chortoicetes terminifera), though the yellow winged locust is "stouter and larger". In north Australian savannas it remains a solitary species. Adult females range from 35 to 50 mm, while males are smaller ranging from 25 to 35 mm. Wikipedia →

Rare
Under 5% of wildlife watchers report an Australian Yellow-Winged Locust sighting in Melbourne on a given day, based on 19 verified sightings from GBIF citizen-science data. It is the 441st 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.
March
In that month about 10% of wildlife watchers report an Australian Yellow-Winged Locust in Melbourne on a given day, against under 5% in April to February, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Australian Yellow-Winged Locust 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 Australian Yellow-Winged Locust sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Acrididae
The closest relatives of the Australian Yellow-Winged Locust that you can see in Melbourne (family Acrididae, Short-horned Grasshoppers) are Wingless Grasshopper (about 10%) and Giant Green Slantface (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Australian Yellow-Winged Locust is recorded against all the insects logged in Melbourne (19 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.
