My Life as a Dragonfly
As a dragonfly, I began life as an egg among pond weeds. In two weeks, I hatched into a nymph, with a spider-like body. I remained a nymph for about two years. All this time, I was underwater eating tasty mosquito larvae, water lice, and small fish. As a nymph, I molted about twelve times, each time shedding my outer skin so that I had room to grow. After two years, I climbed out of the water. When I reached the fresh air, my outer layer split again and I wiggled out, opening my wings for the first time. Hooray! In a few hours, I began flying and catching insects. Over the next few weeks, I searched for a mate. What a life!
Order: Odonata
Size: two to four inches long
Range: marshes, wetlands, parks, and gardens throughout the world

Young dragonflies turn into adults in a process called:
shedding
growing up
metamorphosis
Correct!
Lots of creatures go through a metamorphosis as they grow. Tadpoles turn into frogs, caterpillars into butterflies, and nymphs into adult dragonflies.
A dragonfly nymph is born with gills when it hatches from its egg.
Fact
Gills come in pretty handy when you live underwater! Female dragonflies lay their eggs just above or just below the water surface.
A dragonfly fossil from 250 million years ago has a wingspan of 28 inches -- that's more than 2 feet wide!
Fact
Dragonflies today are much smaller than the ones that flew through the skies during the Permian age. Most dragonflies have wingspans that are about 5 inches.
