This large, fluffy-looking moth is on the wing in July and August, but you might spot a caterpillar at almost any time of year.

This sponge is found on rocky shores around the UK and looks like a thick bready crust (if you use your imagination a bit!).

These moths can be seen flying on sunny days, but you're more likely to spot the fuzzy caterpillars crawling over paths.

Also known as the flat topshell, these are one of the most common and colourful sea snails you are likely to see when out on a rockpool safari!

Brush through a wildflower meadow at the height of summer and you'll hear the tiny seeds of yellow-rattle rattling in their brown pods, hence its name.
