In 3 days ~60% in a week ~90%
Hemigomphus gouldii is a species of dragonfly of the family Gomphidae, known as the southern vicetail. It is a small, black and yellow dragonfly, endemic to eastern Australia, where it inhabits permanent streams and rivers.
The genus name Hemigomphus is derived from the Greek ἡμι- (hēmi, "half"), combined with Gomphus, a genus name derived from the Greek γόμφος (gomphos, "peg" or "nail"), referring to the shape of the male abdomen. The name refers to the close relationship of the genus to Gomphus.

Possible
About 30% of wildlife watchers report a Southern Vicetail sighting in Lamington National Park on a given day, based on 112 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.
December
In that month about 50% of wildlife watchers report a Southern Vicetail in Lamington National Park on a given day, against under 5% in March to September, the lowest months. That is one of Lamington National Park's wettest months, with about 140 mm of rain against 40 mm in August.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Southern Vicetail 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 3 parks where we can rate Southern Vicetail sightings, Lamington National Park has the highest daily chance: about 30%. Next come Springbrook National Park (Australia, about 20%) and Blue Mountains National Park (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Southern Vicetail is recorded against all the insects logged in Lamington National Park (112 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.
