Rare
Under 5% of wildlife watchers report a Cacostomus squamosus sighting in Brisbane on a given day, based on 17 verified sightings from GBIF citizen-science data. It is the 601st 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.

GBIF citizen-science records
It is estimated from how often the Cacostomus squamosus 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.
