Y_Kistochka [10]

Adults of species in the order <u>Coleoptera</u> have 2 wings and the greatest variety of mouthparts.

<h3>Order Coleoptera</h3>

The coleopterans, (order Coleoptera), consist of the beetles and weevils. It is the largest order of insects.

They have two pairs of wings:

  • One of the pair is the hard-shelled outer wings known as the “elytra”. These are not used for flying, but to protect the beetle's flying set of wings and its body as it crawls through narrow passages and tunnels in a tree.

  • The second set of wings is membranous and is folded under the elytra when not in use.
