Damselfly
Damselfly -
Coenagrion puella

Dd

These rather delicate looking insects are actually voracious hunters.  The adults have two pairs of transparent wings which move extremely rapidly and allow the insect to fly very quickly, to hover and even fly backwards.  Their prey is mostly other flying insects which they catch on the wing.

The juvenile damselflies live in freshwater pools and streams.  They hunt with extendible mouthparts that can shoot forwards very quickly to catch their prey, which includes other water insects and even young tadpoles.

Damselflies differ from dragonflies in a number of ways but most noticeably by being more slender and by holding their wings together, over their backs, when resting.
