For some reason, we tend to think that certain creatures do not hear, see, or sleep—just because they look so strange to us. li is true that the grasshopper is a very strange creature indeed, but it has cars and it can hear! There are many varieties of grasshoppers, but in general appearance, they are much alike.
They all have strong jaws and three pairs of legs, and they usually have two pairs of wings. The first pair is leathery and straight. The second pair of wings are membranous and folds underneath the first pair. The hind pair of legs, which is used for jumping, is unusually long and well developed.
Grasshoppers are divided into two general groups depending on the length of their antennae, or horns: the long-horned and the short-horned grasshoppers. The short-horned grasshoppers are sometimes known as “locusts”. The common brownfield grasshoppers are also part of this group. This type of grasshopper “sings” by rubbing its hind legs across its fore wings. And it has “ears” for hearing on its abdomen at the base of the hind legs.
The long-horned grasshoppers, which include the green meadow grasshoppers and the katydids, have antennae that are much longer than their whole bodies. Only the males “sing”, producing the sound by rubbing the bases of the fore wings together. Their “ears” are located on the first pair of legs. So although grasshoppers can hear, they have unusual kinds of ears located in strange places.
