Question

2) The grasshopper sings in​

Answer 1

Answer:

low voice grasshoper sings

Answer 2

Answer:

There are two different mechanisms for singing:

In the one used by the Short-horned grasshoppers, there is a comb-like structure with a row of teeth on the inside of the hind leg, which gets rubbed against a ridge on the wing (a bit like running a stick along a fence very quickly). This produces a ‘chirp’ sound.

The other mechanism used by Crickets and Long-horned grashoppers, there is again a comb-and-ridge mechanism, however, the structures are on the left and right forewings, which rub over each other.
