Nymphs are quite active in their environments, dining on minnows, tadpoles and other aquatic life. The adult dragonfly's time out of the water is considerably less than in the nymph stage.

Dragonfly young, called nymphs, are completely aquatic. Adding a pond, fountain, or a small water feature with plants around the edges is the perfect way to attract dragonflies to your yard.

Yet here is the untapped, unheralded dragonfly, atop the pyramid of predators. There is a catch — dragonflies need clean water bodies to breed and thrive, unlike mosquitoes which can survive even in ...

The nymphs are also fantastic swimmers, using an unusual technique first described in 1975: Jet-propulsion in dragonfly larvae is achieved by the rapid ejection of water from a specialised rectal ...
