Rare
Under 5% of wildlife watchers report a Glistening Blue sighting in Brisbane on a given day, based on 22 verified sightings from GBIF citizen-science data. It is the 474th 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.
May and July–August
In those months about 10% of wildlife watchers report a Glistening Blue in Brisbane on a given day, against under 5% in June and September–April, the lowest months. Those are among Brisbane's driest months, with about 50 mm of rain a month against 160 mm in February.
Only Brisbane, in our data
Brisbane is the only city on Wallace's Line with enough records to rate Glistening Blue sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Lycaenidae
The closest relatives of the Glistening Blue that you can see in Brisbane (family Lycaenidae, Gossamer-winged Butterflies) are Rounded Sixline Blue (about 20%), Speckled Line-Blue (about 20%) and Lesser Grass Blue (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Glistening Blue is recorded against all the insects logged in Brisbane (22 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.
