01 · CuriousIt comes to look at you

Southern hawkers often fly right up to a person, hover for a second, and fly on.

02 · EyesAlmost all eyes

Its two huge eyes meet on top of its head and contain tens of thousands of tiny lenses.

03 · FlightFour wings, four ways

Each wing moves on its own, so it can hover, fly backwards and turn on the spot.

04 · YoungYears under water

The young, called nymphs, live in the pond for two or three years, hunting tadpoles and other insects.

05 · JawA jaw that shoots out

The nymph has a hinged lower lip with hooks that fires forward to grab its prey.

06 · OldOlder than dinosaurs

Dragonflies were flying 300 million years ago. Some then had wings as wide as a crow's.

Six ways to help pond bugs

Dig

Make a pond, any size

Even a washing-up bowl sunk into the ground will have pond skaters on it within days.

Slope

Give it a shallow end

A gently sloping edge lets creatures climb in and out, and warms up quickly in spring.

Fish

Leave out the fish

Goldfish eat dragonfly larvae, tadpoles and almost everything else.

Stems

Plant tall stems

Dragonfly larvae climb up reeds and irises to turn into adults. Without stems they cannot get out.

Rain

Fill it with rain

Tap water is full of plant food and turns a pond green. Top it up from a water butt.

Clean

Clear a little at a time

Remove weed in autumn, a third at a time, and leave it on the edge overnight so that animals can crawl back.

Two lives, one pond

Most pond insects live twice: first for months or years under water, then for a few weeks in the air. A pond without fish is the best place of all to watch both.
