  • They are found everywhere in the world except the Polar Regions.

Physical Features

  • Dragonflies have slender, long bodies.  They are red, green or blue in colour with white, yellow or black markings. 
  • Dragonflies have four large, transparent wings which are fragile and skinny and shine in the sunlight when the insect flies.  Dragon flies have two big compound eyes and two small antennae.

Dragonfly nymph

  • Dragonfly lays eggs.  Some lay eggs in water and others on the stem of plants that grow near water.  When the eggs hatch, the young live in the water.  They hatch after four weeks.  The young are called nymphs.
  • Dragonfly nymphs are short bodied, immature-staged dragonflies that have wing pads and legs located near their head.  They are about the size of eyelashes.  They don’t have wings.
  • The nymphs stay in this stage for about one to two years and shed their skin many times during this period. They live at the bottom of ponds and rivers, among stones, on plants and in leaf litter. 
  • The dragonfly nymphs eat lots of mosquito larvae to help them grow.  They have a special jaw that shoots out from their mouth to grab prey.
  • The nymphs crawl out of the water, emerging as adult dragonflies with wings.

Food habits

  • Mature dragonflies primarily feed on insects like mosquitoes.  They can hunt while they fly.  Their good eyesight helps them to see other flying insects.
  • When dragonflies fly, they hold their legs together, forming a basket in which to capture insects, amazingly, they can eat the captured insects while they are flying.
  • Dragonfly nymphs eat insects, small aquatic animals, and sometimes, young fish, depending on the size of the nymph.
