The Cicadas of Thailand: General and Particular Characteristics Vol. 1 (CD Included.) This is the first of two volumes on Thai cicadas, the most fascinating and also least known representatives of a family of sonorous insects. Cicadas neither sing, nor stridulate, but tymbalize. This study reveals the existence and the double life, larval and imaginal, of cicadas encountered during six years of research in Thailand's sub-mountainous forests. The body of the text includes two chapters discussing general characteristics, acoustic and procreative ethology, and exceptional or enigmatic aspects and behaviour. The text is enriched by drawings and photographs, and accompanied by a CD-Rom which contains 40 cicada sound productions (or tymbalizations), the acoustics made visual in ID and ethological cards, which form an original feature of this pioneering study. There is an index of genera and species and a general index.
