The life cycle of the dragonfly, from egg to death of
adult, is from six months to as much as six or seven years.
Sometimes female dragonflies lay eggs in the small cleft
between mud or moss. Most of their life time is spent
in the larval (nymph) form, beneath the water surface,
using gills to breathe, catching other invertebrates or
even vertebrates such as tadpoles and fish. In the adult
(flying) stage, larger species of dragonfly can live as
long as four months. Dragonflies have very good eyesight
due to their unique eye structure. Dragonflies have about
30,000 facets to their eyes, arranged to give them nearly
a 360° field of vision.
