TheWorld's Largest Insect

This giant insect can be used as a toy.

A child ties one end of a string to a stick and the other endaround the "neck" of an insect. Holding the stick, the child lets theinsect go. With a loud whirring sound, the insect takes off, pulling the stringin a large curve over the child's head. The child laughs as the stick jumpsaround. The child is African, and the toy is the African Goliath beetle, thelargest insect in the world.

The Goliath is a true insect because it has six legs and a bodythat is divided into three parts. Like all beetles, it has two pairs of wings.The front pair are thick and stiff and protect the back pair, which are soft.It is these soft back wings that make the beetle fly forward. They also causethe loud whirring sound the beetle makes when it flies. To steer, the beetletwists and turns its legs the same way you steer a bike by turning its frontwheel.

African children often use the Goliath beetle as a toy. Althoughit is over 15 centimeters long, it is quite harmless.
