Can Grasshoppers Hear?

For some reason we tend to think that certain creatures do not hear, see, or sleep just because they look so strange to us. It is true that the grasshoppers is a very strange creature indeed, but it has ears 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 to pairs of wings is membranous and folds underneath the first pair.

The hind pair of legs, which is used for jumping, in 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 grasshopers are sometimes known as “locusts”. the common brown field grasshoppers are also part of this group. This type of grasshoppers “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 grashoppers, which include the green meadow grasshoppers and the katydids, have antennae which 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 unnusual kinds of ears located in strange places.
