The green hairstreak is the UK's only green butterfly. Look out for the vibrant, metallic sheen of the undersides of its wings on grassland and moorland, and along woodland rides.

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.

Although introduced by humans, the fallow deer has been here so long that it is considered naturalised. Look out for groups of white-spotted deer in woodland glades.

The distinctive sight of a spoonbill is becoming increasingly common in the east and southwest of England, with colonies of breeding birds now established.

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.
