A short, but pretty plant of unimproved grasslands, the Green-winged orchid gets its name from the green veins in the 'hood' of its flowers. Look for it in May and June.

In May, our hedgerows and woodland edges burst into life as Midland hawthorn erupts with masses of pinky-white blossom. During the autumn, red fruits known as 'haws' appear.

The lime hawk-moth is a large, night-flying moth that can be seen from May to July in gardens, parks and woods. It is buff-coloured, with green patches on its scalloped-edged wings.

Bittersweet is a nightshade, so is toxic; its bright red berries may be tempting, but can cause serious illness. Found in hedgerows and gardens, it has purple flowers with yellow stamens.

Unsurprisingly, the chalkhill blue can be found on sunny, chalk grassland sites in southern England. Clouds of this beautiful blue butterfly may be seen fluttering around low-growing flowers.

Horseshoe vetch is a member of the pea family, so displays bright yellow, pea-like flowers and seed pods. Look for this low-growing plant on chalk grasslands from May to July.

Weasels may look adorable, but they make light work of eating voles, mice and birds! They are related to otters and stoats, which is obvious thanks to their long slender bodies and short legs.
