Katydids and bush-crickets

"Katydids and bush-crickets are widely used as subject animals for biologists studying sexual communication - the calls of males to attract sexually responsive females - and mate choice. This book closely examines the practice of "nuptial feeding" by male katydids. Darryl T. Gwynne also emphasizes the methods and practice of insect behavioral research. Gwynne outlines the evolution of katydid and bush-cricket behavior and how it has proven valuable in testing Darwin's theory of sexual selection. These accounts are enriched by many illustrations."--Jacket.
