Jurassic stick insect performed mimicry to defend against predators

Phasmatodea, commonly known as stick insects and leaf insects, are icons of crypsis and primary defense specialization, exhibiting a wide range of remarkable morphological and behavioral modifications associated with camouflage. Most of extant stick and leaf insects have the appearance of abdominal extensions, which has been one of the innovations contributing to their extraordinary crypsis. However, the early origin and evolution of mimetic and defensive strategies within Phasmatodea are meager understanding.
