Tramea transmarina, commonly known as the red glider or northern glider, is a species of dragonfly in the family Libellulidae. The species occurs across islands of the Pacific, northern Australia and parts of Southeast Asia. The type locality is Fiji.
In 1867, Brauer described Tramea transmarina from specimens collected in Fiji. In the same work he also described Tramea samoensis from Samoa, later treated as a synonym of Tramea transmarina. In 1878, Selys described Tramea euryale from material collected in New Guinea and neighbouring islands. The species was later regarded as closely related to Tramea transmarina.
In 1942, Lieftinck described Tramea propinqua from New Guinea and nearby islands, distinguishing it from Tramea transmarina and Tramea euryale by the extent and shape of the dark hindwing patch and differences in the male secondary genitalia.
Some authorities, including the World Odonata List, now treat Tramea propinqua as a synonym of Tramea transmarina, while others such as the Australian Faunal Directory continue to recognise it as a separate species. Tramea transmarina is a medium to large dragonfly with dark patches at the base... Wikipedia →

With luck
About 10% of wildlife watchers report a Red Glider sighting in Khao Sok National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 73rd most-seen of the 104 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
January
In that month about 30% of wildlife watchers report a Red Glider in Khao Sok National Park on a given day, against under 5% in February–March and May–November, the lowest months. That is one of Khao Sok National Park's driest months, with about 70 mm of rain against 280 mm in October.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Red Glider 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 Red Glider sightings, Khao Sok National Park has the highest daily chance: about 10%. Next come Kaeng Krachan National Park (Thailand, about 10%).
Same family: Libellulidae
The closest relatives of the Red Glider that you can see in Khao Sok National Park (family Libellulidae, Skimmers) are Crimson Marsh Glider (about 40%), Common Parasol (about 40%) and Russet Percher (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Red Glider is recorded against all the insects logged in Khao Sok National Park (7 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.
