Hello, I hope this doesn't sound argumentative, but crickets use their wings--not their legs-- to make the chirping sound. They rub one wing, called the "scraper", against the other wing, called the "file" to produce their annoying pulses of sound. I can't remember the name of the crickets that boar under the ground, but they don't chirp because they have no wings. See the link below: http://tinyurl.com/5lt8c2 Gary in TX
