Chirp — the quintessential sound of a cricket. Chirps are short, pure-toned sounds composed of one or more syllables and separated by brief periods of silence. Trill — a long, continuous series of syllables. Pure-toned in the crickets and raspy or lispy in the katydids. Lisp — a brief, but drawn-out soft note, or notes, given by many katydids. Zit — a short, staccato sound made by many katydids.
Grasshoppers detect sound by means of little 'ears' at the base of their abdomen; in crickets these are on the front legs. Most crickets are crepuscular (which means they come out at dusk) whereas grasshoppers tend to be out and about during the day.
