Most insects have membranous wings; such
wings are very thin and like cellophane. Many have venation, a
system of thickened lines in the wings, such as the lacewing. The
wings of butterflies and moths are not membranous. Rather they are
covered with small dust-like scales.
Flies and mosquitoes have one pair of
wings. Some insects - such as the ant and termite - are
wingless. Most insects have two pair of wings. They can be
prominent as in the lacewing and butterfly, or modified to be less
obvious. The beetle's front pair of wings provide a hard or
leather-like covering that protects the back pair when they are not
being used. |
