Tramea basilaris, also known as the keyhole glider, red marsh trotter, or wheeling glider, is a species of dragonfly in the family Libellulidae. It is found throughout most of Africa, Arabia and in Asia. Capable of very long migration and nomadic flight, it reached Europe once, with a pair being recorded at the island of Linosa, Sicily (Italy) in 2016. Similarly, this species is able to use the trade winds to reach the Caribbean and South Americas, where it has been spotted in Bonaire, Venezuela, and Martinique.
It is a medium-sized red dragonfly with extremely long anal appendages. It can be distinguished from other species of this genus by the two brownish black hind-wing patch surrounded by a golden yellow areola in the base. Female is similar to male; but yellowish in color.
This species is found at pools, ponds, marshes, lakes and water tanks. Typical reproducing habitats are grassy marshes and ponds, but this species may be found anywhere during migrations. They are seen in tireless soaring flight in sunny days, sometimes in conspecific groups or in mixed groups of other soaring dragonflies like Pantala flavescens or Hydrobasileus croceus. It perches...

Possible
About 20% of wildlife watchers report a Keyhole Glider sighting in iSimangaliso Wetland Park on a given day, based on 72 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 41st most-seen of the 316 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January
In that month about 30% of wildlife watchers report a Keyhole Glider in iSimangaliso Wetland Park on a given day, against under 5% in May–August and October, the lowest months.
Between noon and 3 pm
Across all the parks we cover, that three-hour window holds the most Keyhole 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.
Yes
Of the 2 parks where we can rate Keyhole Glider sightings, iSimangaliso Wetland Park has the highest daily chance: about 20%. Next come Kruger National Park (South Africa, about 10%).
GBIF citizen-science records
It is estimated from how often the Keyhole Glider is recorded against all the insects logged in iSimangaliso Wetland Park (72 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.
