This book addresses the study of the phylogeny and the evolution of fruit fly (Diptera: Tephritidae) behaviour. It reviews the current state of knowledge and includes considerable new findings on various aspects of fruit fly behaviour, phylogeny and related subjects. In the past, the topics of phylogeny and evolution of behaviour were barely addressed, and when so, often superficially. This text is a definitive treatment, covering all behaviours in a broad range of tephritids, incorporating phylogenies as much as possible.
