Immature crickets resemble their adult versions but lack wings, while older nymphs begin to show the development of wings. Crickets are insects that are usually brown or black in color and are notable for their long antennae and powerful hind legs, which they use to jump great distances.
The jaws of a cricket are strong, and some species are known to bite humans. The cricket's diet is omnivorous and mostly consists of decaying plant matter, fungi and seeds, although they are also known to scavenge their own dead and even prey upon weakened members. The famous chirping of crickets is caused by the rubbing of one wing against the serrated edge of another.
