Rare
Under 5% of wildlife watchers report a Thin-Striped Wattle Cicada 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.
December
In that month about 10% of wildlife watchers report a Thin-Striped Wattle Cicada 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.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Thin-Striped Wattle Cicada sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Cicadidae
The closest relatives of the Thin-Striped Wattle Cicada that you can see in Brisbane (family Cicadidae, Typical Cicadas) are Brown Bunyip (about 10%), Clanger (about 10%) and Black Tree-Ticker (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Thin-Striped Wattle Cicada 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.
