In 3 days ~40% in a week ~70%
Notoaeschna geminata is a species of dragonfly in the family Aeshnidae, known as the northern riffle darner. It is endemic to eastern Australia, occurring north of the Hunter River, New South Wales, where it inhabits rapid streams.
Notoaeschna geminata is a large, dark brown to black dragonfly with yellow markings. It appears similar to Notoaeschna sagittata, the southern riffle darner, which occurs south of the Hunter River. The genus name Notoaeschna is derived from the Greek νότος (notos, "south" or "the south wind"), combined with -aeschna, a suffix commonly used for dragonflies associated with the Aeshna group. The name refers to a southern representative of that group.
The species name geminata is derived from the Latin geminatus ("doubled" or "paired"), referring to abdominal spots divided into two halves. List of Odonata species of Australia Wikipedia →

Possible
About 20% of wildlife watchers report a Northern Riffle Darner sighting in Springbrook National Park on a given day, based on 70 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 26th most-seen of the 429 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
October
In that month about 40% of wildlife watchers report a Northern Riffle Darner in Springbrook National Park on a given day, against under 5% in February–June and August–September, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Northern Riffle Darner sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 2
Of the 2 parks where we can rate Northern Riffle Darner sightings, Springbrook National Park ranks 2nd at about 20%. The best odds are in Lamington National Park (Australia, about 30%).

GBIF citizen-science records
It is estimated from how often the Northern Riffle Darner is recorded against all the insects logged in Springbrook National Park (70 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.
