click beetles are slender and elongate in shape and range from about
4 to 50 millimetres in length. They are usually drab-coloured and
have serrated antennae. Adults are nocturnal and are often attracted
to lights at night. They sometimes enter houses and can often be
seen on the bark of trees and flowers.
larvae of click beetles are commonly known as wireworms. They are elongate
and cylindrical in shape, have hardened abdominal segments and are usually
shiny yellow to orange-brown in colour. They may be either herbivorous,
feeding on plant roots or carnivorous and feed on other insect larvae
and soft-bodied invertebrates.
beetles are a favourite with children as they can arch their backs and
flick up into the air with a distinct clicking sound. This is made possible
due to a peg-like structure which projects backwards from the underside
of the prothorax and fits into a cavity in the mesothorax.
click beetle bends its body to enable the peg to snap into the cavity
causing its body to straighten so suddenly that it somersaults into the
air. This jumping is a defence tactic that allows the beetle to evade
