Violet coral
The branching, finger-like projections of this fungus give it the appearance of an underwater coral. Its striking colour and form make it easy to spot, but it is scarce in the UK.
Violet ground beetle
Violet ground beetles are active predators, coming out at night to hunt slugs and other invertebrates in gardens, woodlands and meadows.
Violet sea slug
Despite its dazzling colouration, this fabulous nudibranch can be easily missed, due to its small size!
Viper's-bugloss
The upright, blue flower spikes of Viper's-bugloss can be spotted on chalk grassland, sand dunes, cliffs and banks. Its spotted stem is thought to resemble a viper.
Wall barley
The distinctive spiky, or 'bearded', green flower heads of wall barley appear from June to July and are easy to spot in an urban environment as they push their way up through pavements and walls.
Wall brown
The wall brown or 'wall' gets its name from the fact it rests on any bare surface or wall! It can be found in open, sunny places like sand dunes, old quarries, grasslands and railway cuttings.
Wall-rue
With club-shaped leaflets on its fronds, wall-rue is easy to spot as it grows out of crevices in walls. Plant it in your garden rockery to provide cover for insects.
Warty venus
This bumpy shell lives up to its name and lives partly buried in the seabed along the west coast of Great Britain.
Wasp beetle
A clever mimic, the wasp beetle is black-and-yellow and moves in a jerky, flight-like fashion - fooling predators into thinking it is actually a more harmful common wasp. Look for it in hedgerows and woods in summer.
Wasp spider
The wasp spider is a great mimic - looking just like a common wasp keeps it safe from predators, even though it is not dangerous itself. It can be found in southern England, but is spreading north.
Water avens
Look for Water avens in damp habitats, such as riversides, wet woodlands and wet meadows. It has nodding, purple-and-orange flowers that hang on delicate, purple stems.
Water dock
As its name suggests, Water dock likes damp places, such as the egdes of canals, ponds and rivers. It is a tall plant with large, greenish flower spikes.
