About The Cover

Femalecrickers are drawn to males of the same species by the male's callingsong. By placing a tethered female upon a Y-maze and placing loudspeakers on her right and left, her responsiveness to various songs can be directly measured (actual size of cricker, 1 inch in length). See page 82.[C. Walcott, Biology Department, State University of New York, Stony Brook]
