The Brown argus favours open, chalk and limestone grasslands, but can also be spotted on coastal dunes, in woodland clearings and along disused railways.

As the name suggests, this beautiful brown butterfly is most common in Scotland, though it can also be seen in northern England.

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.

Considered to be one of the prettiest gentians, the Chiltern gentian is a rare plant in the UK. It likes chalk grasslands, its purple, trumpet-shaped flowers blooming from August.
