Final answer:
Grasshoppers have two pairs of wings, front and back. The front ones (tegmina) are more rigid and provide protection while the back ones are membranous, function in flight, and tuck away beneath the tegmina when not in use.
Step-by-step explanation:
A grasshopper has two pairs of wings: the front pair and the back pair. The front wings, also known as tegmina, are generally narrow and leathery, which provide protection. They are not typically used for flight but cover and protect the more delicate hind wings when the grasshopper is at rest. On the other hand, the back wings are wider, thinner, and membranous. They are hidden beneath the tegmina when not in use, but during flight, they unfold to their full size. These wings are necessary for the grasshopper's flight and are thus integral to its ability of locomotion and evading predators.
