In 3 days ~60% in a week ~90%
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 30% of wildlife watchers report a Northern Riffle Darner sighting in Lamington National Park on a given day, based on 135 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 19th most-seen of the 430 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
October and December
In those months about 50% of wildlife watchers report a Northern Riffle Darner in Lamington National Park on a given day, against under 5% in February to 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.
Yes
Of the 2 parks where we can rate Northern Riffle Darner sightings, Lamington National Park has the highest daily chance: about 30%. Next come Springbrook National Park (Australia, about 20%).

GBIF citizen-science records
It is estimated from how often the Northern Riffle Darner is recorded against all the insects logged in Lamington National Park (135 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.
