I came upon this dainty Long Legged Marsh Glider (Trithemis pallidinervis), precariously perched on a reed stump at Mallyadi, Kundapura. Long-legged Marsh Gliders are usually encountered around ponds, lakes and rivers, being at home in wetlands and are fascinating, graceful insects. While at rest during the hotter parts of the day, they tend to raise their long abdomen upwards, with the tip pointing at the sun, assuming a curious stance, much like a gymnast doing a handstand. This Posture is called an obelisk and helps avoid overheating.

I was using Canon EF 100-400mm F4.5-5.6L IS II USM Zoom Lens on Canon EOS 80D Camera. Owing in part to the distance between us, the dragonfly continued to perch, undisturbed. Trying to focus on a tiny subject in the fast breezy environment, using a long focal length is not an easy task. I utilized 1/500sec shutter speed and f/5.6 aperture at ISO 200 to get this picture.

Trithemis pallidinervis is a medium-sized, yellow-brown dragonfly with long spidery legs. Males have yellow to pale brown faces in front and are iridescent purple above. The large compound eyes are reddish brown above, brownish on the sides and bluish grey below. The thorax is olivaceous-brown above, with a dark brown triangle, bright yellowish brown below, with three black stripes on each side. Legs are black, long and spidery. The basal half of the femora of the first pair of legs are bright yellow. Wings are transparent with reddish venation. The forewings have amber coloured basal markings. The wings have a golden sheen when viewed from a certain angle. Wing spot is black with creamy white ends. The abdomen is a bright yellow with black median and lateral stripes. These stripes are confluent at the end of each abdominal segment, enclosing a wedge-shaped yellow spot.

Females largely resemble males, with the wings, tinted yellow or reddish brown, with the base of the abdomen being broadly black.The species is partial to the marshlands and weedy ponds where it breeds, preferring to perch on tall aquatic weeds or at bare ends of shrubs. The long legs are very noticeable at this time.
