Damselfly nymphs live underwater for one or two years, but the adult insects live for only a few weeks.

EXPERIMENT

POND DIPPING

Try pond dipping to find insect nymphs and larvae. For safety, make sure you go with an adult.

You will need:

• a net or kitchen sieve • a tray or other shallow container (preferably white) • a strainer and spoon to scoop out creatures • a smaller container for individual creatures • a magnifying glass

1. Put some pond water in your tray.

2. Sweep your net or sieve back and forth in the pond, then tip its contents into your tray. What have you netted?

3. Try dipping at different levels in the pond. Did you find different creatures?

4. Use the pictures on this page and information from reference books and the Internet to identify some of the creatures you discover.

5. When you have finished, put your finds back in the pond at the place where you found them.
