Austrogomphus ochraceus, also known as Austrogomphus (Austrogomphus) ochraceus, is a species of dragonfly in the family Gomphidae, commonly known as the jade hunter. It inhabits streams, rivers and lakes in eastern Australia from north of Brisbane through New South Wales to Victoria.
Austrogomphus ochraceus is a tiny to medium-sized, black and yellow dragonfly. The genus name Austrogomphus combines the prefix austro- (from Latin auster, meaning “south wind”, hence “southern”) with Gomphus, a genus name derived from Greek γόμφος (gomphos, “peg” or “nail”), alluding to the clubbed shape of the abdomen in males.
The species name ochraceus is derived from Greek ὤχρα (ōchra, "yellow ochre"), likely referring to the yellow markings on the thorax, legs, and abdomen. List of Odonata species of Australia Wikipedia →

Rare
Under 5% of wildlife watchers report a Jade Hunter sighting in Sydney on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 393rd most-seen of the 742 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.
December
In that month about 10% of wildlife watchers report a Jade Hunter in Sydney on a given day, against under 5% in January to November, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Jade Hunter sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Sydney, in our data
Sydney is the only city on Wallace's Line with enough records to rate Jade Hunter sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Jade Hunter is recorded against all the insects logged in Sydney (14 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.
