They do this by rubbing their legs and wings together. Sometimes, grasshoppers also make loud snapping noises when they fly. This may be another way for males to attract females. Grasshoppers change their form during their lifetime. This is called metamorphosis.
Grasshoppers undergo simple metamorphosis.
The female squeezes out eggs into the ground through the tip of her pointy abdomen. She swallows air to blow up her abdomen so it can push deep into the soil. She covers the eggs with a white frothy materials which protects them. It makes a case around them. The adult grasshopper then dies in the autumn.
