This account deals with all species of Orthopteroidea recorded in the islands. The Orthopteroid insect orders comprise the crickets, katydids and grasshoppers (Orthoptera), stick and leaf insects (Phasmatodea), web-spinner (Embiidina) and the Dictyoptera (termites, cockroaches, mantises and earwigs). This is an early group of insects, dating back some 300 million years.
Distributions are given and the conservation status discussed using the IUCN Red List criteria (IUCN 2001) and following the assessment in Gerlach et al. (2005). Non-native species have not been assessed. For most genera a representative species is illustrated (Plates 1-4).
