Distribution and habitat:

Tramea limbata Ferruginous Glider Distribution Map May 2020Flies in warm, humid  eastern, northern and north eastern areas of South Africa as well as the WCP and ECP..
As records become available one will probably find the over the entire region. 
They disperse well, often swarming together with
Pantala flavescens, likewise following rains and breeding in seasonal pools and marshes.
From 0 to 1800 m above sea level, but mostly below 900.

Behaviour:
  • Males fly between bushes and trees continuously for long periods, resting by hanging like a pendulum in sheltered places.
  • However often perch in the ‘pennant’ position at the end of high or exposed stakes, with wings raised and abdomen either also slightly up or pressed down. 
  • Often disturb other species at the pond
  • Range from close to water to quite a distance away from the breeding water.
  • In flight, the pattern of the dark red body and the narrow brown band at the base of the wing is diagnostic.
