Hemigomphus heteroclytus is a species of dragonfly of the family Gomphidae, known as the stout vicetail. It is a small, black and yellow dragonfly, endemic to eastern Australia, where it inhabits streams that reduce to trickles in summer.
Hemigomphus heteroclytus is similar to Hemigomphus gouldii, the southern vicetail, also found in eastern Australia. 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.
The species name heteroclytus is derived from the Greek ἕτερος (heteros, "other" or "different") and κλυτός (klytos, "renowned", "glorious" or "splendid"), likely referring to the presence of a yellow half-collar, absent in other members of the genus Hemigomphus.

Possible
About 20% of wildlife watchers report a Stout Vicetail sighting in Springbrook National Park on a given day, based on 62 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 15th most-seen of the 429 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
December
In that month about 40% of wildlife watchers report a Stout Vicetail in Springbrook National Park on a given day, against under 5% in March to August, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Stout Vicetail sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 parks where we can rate Stout Vicetail 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 Stout Vicetail is recorded against all the insects logged in Springbrook National Park (62 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.
