Anoplognathus pallidicollis
In 3 days ~10% in a week ~30%
Anoplognathus pallidicollis is a relatively large beetle of the family Scarabaeidae, native to Australia. The beetle has a life span of 24 months and it grows up to 20 mm in length. Adults were once common in the summer months, particularly around Christmas, resulting in the common name of Christmas beetle for the species (and also for other members of its genus).
The beetles have rich glossy brown elytra and clypeus, and clawed legs covered in multiple barbs. Like all Anoplognathus species, the forelegs are of uneven lengths, possibly to better enable them to cling to thin Eucalyptus leaves.
The beetles are nocturnal, and are attracted to lights at night. They can often be found around outdoor lighting or crawling into homes. Studies show that they are most active around sunset and the hours immediately after.
Their numbers are believed to be in decline, most likely due to habitat loss. Wikipedia →

With luck
About 10% of wildlife watchers report a Cashew Beetle sighting in Brisbane on a given day, based on 37 verified sightings from GBIF citizen-science data. It is the 333rd 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 30%, if each day is a fresh chance.
October to December
In those months about 10% of wildlife watchers report a Cashew Beetle in Brisbane on a given day, against under 5% in January to September, the lowest months.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Cashew Beetle sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Cashew Beetle is recorded against all the insects logged in Brisbane (37 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.
