It was the most beautiful I encountered along the bank of a river I visited recently. It flies and lands on the dry stalks of Calotropis gigantea or the crown flower. Of course, it monitors and occasionally flies in ambush of prey, perhaps mosquitoes or other flying insects. The fourth image from above shows a scene after it ambushes its prey in midair (seems something is upside down or doesn't look normal there).
Among the other plants and insects there, it must have looked very striking with its fiery red color. I immediately aimed my shot, but I didn't want it to panic and fly away. I approached it slowly, and of course, admiring it. It was the male Scarlet (Crocothemis erythraea), or Scarlet Darter.
Look at his abdomen, it looks wide. It has transparent wings, the veins on the wing edges appear red and orange from the base of the wing to the tip, with a stigma that I think is orange.
It is a dragonfly that inhabits open water habitats (flowing or stagnant) as well as the place where I found it in Aceh, Sumatra (Indonesia).
