Organisms in my garden - Dragonflies (Odonata sp.)


I was recording some tadpoles, when I saw a beautiful dragonfly larvae climbing up a water plant stem. 


What is it?

A dragonfly is an insect. A year or two of their lives are spent as nymphs, living in fresh water.
Adults only fly for a couple of weeks, finding a mate to reproduce and then dying.  There are at least 3000 species of dragonfly, they are found on every continent except for Antarctica. An adult dragonfly has three body parts, the head, thorax and abdomen. It is a large insect, about 8-9 cm in length. The legs are not used for walking, but are used for holding prey and for perching and climbing on plants.     

What do they eat?

Dragonflies eat insects, particularly midges and mosquitoes. They will also eat butterflies, moths, aphids and even smaller dragonflies!!

What eats them?

Birds, spiders, frogs and larger species of dragonflies.

Life cycle

Egg, nymph then adult.
