Just emerging after developing on the little pond in the garden.
I think it’s a species of Orthemis, in the Libellulidae family. The males are very territorial and usually red or purple colored, whereas the females are dark brown. I’ve seen females laying eggs in the pond, and the male looking over his territory from some branches nearby. This dragonfly was seen on Eichhornia, the water hyacinths we have on the pond, Saturday October 15, 2011.
