This field guide covers northern to central Tanzania, southern Kenya and parts of central Kenya. Most species are illustrated by live specimens; generally, adult males and females are depicted, along with selected nymphal stages. For species-rich genera, morphological details are provided, together with keys to genera and species as well as distribution maps for most taxa. The enclosed DVD features the songs of 185 species.
