Rare
Under 5% of wildlife watchers report a Zosteria sydneensis sighting in Blue Mountains National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 611th most-seen of the 789 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.
January–March and October–November
In those months about 10% of wildlife watchers report a Zosteria sydneensis in Blue Mountains National Park on a given day, against under 5% in April–September and December, the lowest months.
Between 4 and 7 pm
Across all the parks we cover, that three-hour window holds the most Zosteria sydneensis sightings with a recorded time, and about half of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Blue Mountains National Park, in our data
Blue Mountains National Park is the only park on Wallace's Line with enough records to rate Zosteria sydneensis sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Zosteria sydneensis is recorded against all the insects logged in Blue Mountains National Park (6 verified sightings from 2019 to 2026), 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.
