There are several species of Click Beetle in the UK, all long, slender
with tapering body and a hinge between the long thorax and abdomen. Also called Skipjacks, they are
able to vault themselves into the air with a loud click. They do this for two reasons: to right
themselves when they have fallen on their back or to startle and evade a predator.
They are vegetarian but their larvae (wireworms) can be a pest to root crops.
The Red-brown Skipjack is native to much of Eurasia and is common in Britain. It is some 12-15mm long
and has red-brown wing cases tapering at the back and a blackish extended thorax, both covered in fine hairs. The legs
are brown. While the image above right is poor, it shows the scutellum knob that is a key part of the click mechanism.
They are found in different countryside habitats.
The Common Click Beetle is native to most of the UK, to much of Europe (not far north)
through to Central Asia and to part of North Africa. It is a dark reddish brown from head, extended thorax and
tapered wing cases. Above centre shows the click lever mechanism on the scutellum to release the hinge.
It is some 7-9mm long and is attracted to light.
Wireworms are larvae of click beetles. They live in the soil 2-4 years and eat roots and seeds.
Of the many different species in the UK, only 3 are serious pests to root crops, including the larvae of the Common Click Beetle above.
It grows to some 20mm.
