This charming little warbler is an increasingly common sight in autumn, when migrants pass through the UK.

Traditionally a coastal species, Lesser sea-spurrey has spread inland, taking advantage of the winter-salting of our roads. Its pink-and-white flowers bloom in summer.

Spiny lobster, crawfish, crayfish, rock lobsters - many names, one animal! This pretty lobster was made extinct in many areas through overfishing, but is now making a slow comeback.

This large shieldbug lives up to its name, bristling with long pale hairs. It's a common sight in parks, hedgerows and woodland edges in much of the UK.

The marsh hair moss is the largest moss in the UK. Look out for it in damp woodland and on boggy heathlands where it forms large, green and spikey 'cushions'.

Familiar as the bristly plant that easily hooks on to our clothing as we walk through the countryside or do the gardening, cleavers uses its hooks to help it climb and to disperse its seeds.
