Psaltoda harrisii
In 3 days ~10% in a week ~20%
Psaltoda harrisii, commonly known as the yellowbelly, is a species of cicada native to eastern Australia. It can be distinguished from the similar but larger Black prince (Psaltoda plaga), by noting the absence of a dark Z-shaped infuscation near the apex of the forewings, which is present on P. plaga.

Rare
Under 5% of wildlife watchers report a Yellowbelly sighting in Brisbane on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 575th 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.
December
In that month about 10% of wildlife watchers report a Yellowbelly in Brisbane on a given day, against under 5% in January to November, the lowest months. That is one of Brisbane's wettest months, with about 130 mm of rain against 40 mm in July.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Yellowbelly sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 2 cities where we can rate Yellowbelly sightings, Brisbane ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Sydney (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Yellowbelly is recorded against all the insects logged in Brisbane (17 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.
