119. Tramea transmarina euryale (Brauer, 1867)

Number: 119
Family: Libellulidae
Genus:  Tramea
Species:  Tramea transmarina euryale
Common name(s): Ocean Glider, Saddlebag Glider
Thai name(s): แมลงปอบ้านใหญ่เปลี่ยน
Habitat: Exposed (yet tree-lined), upland natural ponds
Location(s): Khao Yai National Park (22/04/2011), Phu Man NP (Khon Kaen)
Sightings (by me): Uncommon (There were 4 males @ Khao Yai)
In flight (that I have seen): April (longer, I'm sure)

Another species I saw alongside Indothemis limbata limbata, was Tramea transmarina euryale. There were 4-5 males constantly patrolling the edges of the pond. I watched them for about 30 minutes and almost gave up on waiting for one land to take photos. However, my luck was in and a male landed in the bushes behind me, just while there was enough light left. Once it had landed, it wasn't easily frightened and both photos below are uncropped, using a 300 mm lens.

The male
It's similar in size and shape (including the long legs) of Trithemis pallidinervis. The thorax is brown and the abdomen is a strong red, with prominent dorsal marks on S8-9. The caudal appendages are black and very long. There is also red colouration to the base of the wings.
