In biology, the modified forelimb of birds
and bats, or the membranous outgrowths of the
exoskeleton of insects, which give the power
of flight. Birds and bats have two wings.
Bird wings have feathers attached to the
fused digits (`fingers') and forearm bones,
while bat wings consist of skin stretched
between the digits. Most insects have four
wings, which are strengthened by wing veins.
The wings of butterflies and moths are
covered with scales. The hind pair of a fly's
wings are modified to form two knoblike
balancing organs (halteres).
