Tramea loewii, commonly known as the common glider, is a species of dragonfly in the family Libellulidae. It occurs from Indonesia and New Guinea through Australia and the western Pacific to New Caledonia. The species is recently self-introduced to New Zealand.
Tramea loewii is a medium to large dragonfly with dark patches at the base of the hindwings, a striped thorax, and a red abdomen in males. In 1866, Brauer published the description of Tramea loewii using the manuscript name proposed by Kaup. Brauer noted that Kaup had already assigned names to many specimens sent to him for study, and that he generally retained those names unless they were already occupied.
In 1942, Lieftinck reviewed Indo-Australian populations of Tramea loewii and described the Australian form as Tramea loewii tillyardi. He regarded the Australian populations as closely related to specimens from Ceram and western New Guinea, differing mainly in thoracic colouration and minor differences in the male genitalia.
Tramea tillyardi is now treated as a synonym of Tramea loewii. Tramea loewii is a medium to large dragonfly with a wingspan of about 85 mm and a body length of... Wikipedia →

Possible
About 20% of wildlife watchers report a Common Glider sighting in Nitmiluk National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 16th most-seen of the 17 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.
May
In that month about 40% of wildlife watchers report a Common Glider in Nitmiluk National Park on a given day, against under 5% in April and September–October, the lowest months. That is one of Nitmiluk National Park's driest months, with almost no rain against 270 mm in January.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Common Glider sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 6
Of the 6 parks where we can rate Common Glider sightings, Nitmiluk National Park ranks 2nd at about 20%. The best odds are in Kakadu National Park (Australia, about 30%).
Same family: Libellulidae
The closest relatives of the Common Glider that you can see in Nitmiluk National Park (family Libellulidae, Skimmers) are Scarlet Percher (about 70%), Blue Skimmer (about 40%) and Pygmy Percher (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Glider is recorded against all the insects logged in Nitmiluk National Park (5 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.
