With luck
About 10% of wildlife watchers report a Plain Box-Owlet sighting in Brisbane on a given day, based on 128 verified sightings from GBIF citizen-science data. It is the 113th most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
February
In that month about 20% of wildlife watchers report a Plain Box-Owlet in Brisbane on a given day, against under 5% in May to September, the lowest months. That is one of Brisbane's wettest months, with about 160 mm of rain against 40 mm in July.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Plain Box-Owlet sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Plain Box-Owlet sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Plain Box-Owlet is recorded against all the insects logged in Brisbane (128 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.
