Over 260 stick- and leaf-insects (phasmids) are described and illustrated by biogeographical zone. These descriptions allow non-specialists to help identify the presented species and learn about habitat, foodplants and distribution. Phasmid systematics are approached from perspectives of taxonomy and phylogeny, along with bibliographic notes on major phasmid explorers and main publications. An extensive checklist of currently described species and their distribution is included. Furthermore, this book covers phasmid biology (anatomy, main biological functions, ecology) as well as basic advice on collecting and rearing phasmids. Trivia like myths and legends on phasmids and pop culture references are also presented.
