Many insects attract our attention by their production of audible noises.
Some of these are so common that they help define seasons for us, such as the daytime buzzing of dog day cicadas in midsummer or the song of tree crickets at night . . . Bugs don t have bones, but they do have a skeleton. The insect skeleton is on the outside of the body and covers the muscles and inner body parts . . .

A moth touching the water s surface will find itself stuck there, and in its struggle to get free, it will send a series of ripples across the water . . .
