Some rub their legs and their wings, while others rub their legs against their head or their wings against their body. The most well known insects that use stridulation to produce sound are the crickets (rub their wings together) and grasshoppers (rub legs or leg and wing), but some ants, wasps, and beetles also use stridulation.
Behavior and habits of crickets Crickets have long antennae (as long as their body or longer) and large back legs, which they use for jumping or hopping. Male crickets chirp by rubbing their wings together. Adult females have a sword-like egg-laying device extending backwards from the tip of the abdomen.
Crickets stridulate ("sing") by rubbing their wings together, while grasshoppers stridulate by rubbing their long hind legs against their wings. Grasshoppers detect sound by means of little 'ears' at the base of their abdomen; in crickets these are on the front legs.
Cricket Wing Functions. Flight is just one of the important functions provided by cricket wings, the other being use of wings to communicate with other crickets by their chirping sounds. To produce the chirping sounds common to crickets they rub their hind legs on their wings or rub their wings together.

Crickets will rub their legs together as a way of cleaning off the dirt. Their ears are located under the knees of their legs. This means that, for the ears to remain sensitive, they must be kept clean always.
Grasshoppers and locusts have a row of pegs like a comb on their back legs. They scrape these pegs against the hard edges of the front wings to make sounds. Crickets and katydids produce sounds by rubbing their wings together. In order to hear these sounds, orthopterans have a tympanum (ear) on each front leg, just below the knee.
What insect makes noise with their legs? Katydids, also known as bush crickets (Mecopoda elongata), are among a handful of insects that make noise by rubbing a hind leg on one wing.
Crickets produce sound by rubbing their wings together while grasshoppers rub their hind legs against their wings. The way these two insects detect sound is also different. Grasshopper ‘ears’ are located at the base of their abdomen, but crickets sport them on their front legs.
