In 3 days ~20% in a week ~40%
Hemicordulia continentalis is a species of dragonfly in the family Corduliidae, known as the fat-bellied emerald. It inhabits pools, lakes, ponds and swamps in coastal Queensland and northern New South Wales, Australia. Hemicordulia continentalis is a small to medium-sized, black and yellow dragonfly with long legs. The male abdomen is swollen giving the appearance of a club. In both males and females the inboard edge of the hindwing is rounded.
The genus name Hemicordulia is derived from the Greek ἡμι- (hēmi, "half"), combined with Cordulia, a genus name derived from the Greek κορδύλη (kordylē, "club" or "cudgel"). The name refers to the close relationship of the genus to Cordulia.
The species name continentalis is the Latin word for "continuous", "uninterrupted", or "forming a connected whole". The name may refer to the species being regarded as intermediate between Hemicordulia assimilis and Hemicordulia novaehollandiae.

With luck
About 10% of wildlife watchers report a Fat-Bellied Emerald sighting in Brisbane on a given day, based on 140 verified sightings from GBIF citizen-science data. It is the 149th most-seen of the 1083 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Fat-Bellied Emerald in Brisbane on a given day, against under 5% in April to October, 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 Fat-Bellied Emerald sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Fat-Bellied Emerald is recorded against all the insects logged in Brisbane (140 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.
