Damselflies and dragonflies are related insects of the Order Odonata.

Dragonfiles are suborder ~ Anisoptera
Damselflies are suborder ~ Zygoptera
There are estimated to be more than 4,700 species worldwide! Dragonflies and damselflies begin their life underwater, hatching from eggs and spending their first stage of life as aquatic larva or nymphs. During this stage of their lives they breath through gills and are ferocous aquatic predators, feeding on other aquatic larva, tadpoles and small minnows.

As nymphs, it is very easy to tell damselflies and dragonflies apart. A damselfly nymph has a long, slender body with three, feathery tail-like gills which allow it to breath underwater. It moves through the water by sort of wriggling from side to side.

By comparison, the dragonfly nymph looks stocky and stubby, with a wide, thick abdomen. In it's abdomen is a special gill chamber. The dragonfly nymph moves and breathes by pumping water through this chamber and is capable of propelling itself very quickly through the water by expelling water through these gills.

Hello Iris !

Tough one here . A bit too narrow depth of field. The image would have been great. Here we have our two subjects out of focus. Nevertheless a good subject and composition. A bit surprising at F6.3.
Cheers!
Robert
