Popplepsalta notialis notialis (Popple, 2013) is also known as the southern red-eyed squeaker. The length of the forewing is 13–17 mm. P. n. notialis occurs from Mount Moffatt in Central Queensland southwards through South East Queensland to Gerroa on the south coast of New South Wales. Associated habitats include eucalypt woodland and open forest, as well as urban parks and gardens in Sydney.
Adult males may be heard from September to February, while clinging to the foliage and upper branches of trees and shrubs, emitting buzzing and chirping calls. Popplepsalta notialis incitata (Popple, 2013) is also known as the inland sprinkler squeaker.
The length of the forewing is 14–16 mm. P. n. incitata occurs in the Brigalow Belt of inland eastern Australia, from Mazeppa National Park in central Queensland southwards... Wikipedia →

GBIF citizen-science records
It is estimated from how often the Southern Red-Eyed Squeaker is recorded against all the insects logged in Sydney (159 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.
