The Coppery click beetle is a large, narrow beetle that is found on grassland and farmland; the larvae (known as 'wire worms') live underground where they feed on roots and can cause damage to potato crops. Click beetles are known for their jumping abilities: by arching their backs they create tension in a special hinge in their thorax, which they can release suddenly, causing them to flip out of the way of danger. They can leap at speeds of more than 2 metres per second, creating a clicking noise as they do so. There are 65 species of click beetle in the UK, of which, the Coppery click beetle is one of the largest.
