More About Beetles ...
|
Beetles (order Coleoptera) are one of the main groups of insects. The order has more species in it than any other order in the entire animal kingdom. 40% of all animal species are beetles (about 350,000 species), and new species are regularly discovered.
The forewings of beetles are transformed into hard shells, called elytra. These elytra form an armour protecting the abdomen and the sensitive hindwings. The forewings are not used (at least not actively flapped) in flying, but they must (in most species) be raised in order to move the hindwings. After landing the hindwings are folded below the elytra. Most beetles can fly, but few reach the dexterity of some other groups, e.g. flies, and many species only fly if absolutely necessary. Some beetles have elytra that have grown together and cannot fly at all; a few have lost their wings altogether.
Some beetle larvae (young) are leaf miners.
Beetles can be found in almost all biotopes, but are not known to occur in the sea or in the polar regions.
Beetles are endopterygotes with complete metamorphosis. The larva of a beetle is called a grub.
