General Dragonfly Facts

You've probably seen a dragonfly in real life, but how much do you really know about these flying creatures?

  • Dragonflies have inhabited Earth for more than 300 million years.
  • There are more than 5,000 different species of dragonflies.
  • Dragonflies come in a wide array of beautiful colors, including yellow, red, brown, and blue. Some are iridescent in areas.
  • Because dragonflies require water to reproduce, their habitats are near water. Any water will do, from a natural body of water to a manmade backyard pond.
  • Dragonflies thrive in warm climates. They need to take in warmth from the sun before they start flying on their neverending quest for food.
  • Dragonflies do not have stingers, and they generally do not bite people.
  • The term for a group of dragonflies is "swarm."
  • Many people believe it is good luck for a dragonfly to land on your head.

Facts About Dragonfly Larvae/Nymphs

Discover some interesting facts about dragonfly larvae, which are also called nymphs.

  • After breeding, female dragonflies lay eggs on water or in an area that will fill with water.
  • Once the eggs hatch, they become aquatic larvae called nymphs.
  • Dragonflies stay in nymph form for up to four years, depending on species.
  • Dragonfly nymphs molt several times. Molting frequency varies by species, ranging from 8 to 17 times.
  • Dragonfly nymphs function as predators. They prey on larvae of other insects as well as tiny fish and tadpoles.
  • When it is time, the larvae will emerge from the water to metamorphosize into adult dragonflies.
  • During the metamorphosis, the dragonfly's wings, abdomen and exoskeleton emerge from the nymph.

Facts About Adult Dragonflies

Things are very different for adult dragonflies than for nymphs.

  • Once the metamorphosis is complete, the creature enters its general phase. It is weak and vulnerable until its wings dry and it gains strength.
  • Once the dragonfly gains strength, it takes to the air and begins feeding on flying insects caught in the air.
  • Their favorite insects to eat include cicadas, gnats, flies, and mosquitoes. Larger dragonflies will even eat smaller dragonflies.
  • Some people mistakenly believe that adult dragonflies only live one day, but this is not accurate other than in cases where a predator would strike on day one.
  • Adult dragonflies typically weigh just over a tenth of an ounce.
  • Their wingspan generally reaches from two to five inches wide.
  • The typical lifespan of a dragonfly is just a few months. They generally live just long enough to reproduce before falling victim to a predator.
  • Adult dragonflies have many predators, which is why their adult lifespan tends to be only a few months.
  • Common dragonfly predators include birds, fish, ducks, frogs, and lizards.
  • It is much more likely that a dragonfly will die because of a predator rather than its age.
