Dragonflies
ORDER: Odonata
SUBORDER: Anisoptera
(The order Odonata consists of two suborders Anisoptera (dragonflies) and Zygoptera (damselflies)

The adults can be differentiated by the fact that the wings of most dragonflies are held perpendicular to the body when at rest. Whereas the adult damselfly hold their wings along their body.

The larval stages of both the suborders are aquatic and can be distinguished by the placement of the gills. Dragonfly larvae suck water into their abdomen and move it over their internal gills. Damselfly larvae have gills at the end of the body as three appendages.
