Orthemis is a neotropical genus of dragonflies in the order Odonata, subordem Epipocrita (= Epiproctophora), infraorder Anisoptera, superfamily Libelluloidea, family Libellulidae and subfamily Libellulinae. The males and females of Orthemis possess varying tones in coloration as can be seen in a link below. In all, this is a male.

There is a wing membrane surrounding the hyaline nodus with a black costal vein. 10 abdominal segments seem to be present. Through observation alone and measuring with a ruler without a specimen in hands, I believe the wingspan lies somewhere around 105mm or close. Males in this genus tend to have more impacting colors than females.

Supposedly, they are of Neotropical distribution.

Adults of Orthemis are aerial hunters and will predate insects in general. Their eyesight is pretty much on pair with all Odonata I've seen. They are often seen perching on a twig and can be found in humid habitats, most often forests, suburban and rural habitats.
