European Praying Mantis

Mantis religiosa is the most widely distributed praying mantis in the world, found from Europe and Africa through North America, where it was introduced in the 1890s. The forelegs are armed with rows of needle-like spines that snap shut on prey in less than 60 milliseconds — among the fastest predatory strikes ever measured. Mantises are the only insects with true binocular stereoscopic vision; their compound eyes have a high-acuity 'fovea' that lets them judge depth precisely. The head sits on a long flexible neck that rotates a full 180 degrees, giving the predator a panoramic search range no other insect matches. Sexual cannibalism — females eating males during or after mating — has been documented in roughly 30% of laboratory pairings, though field rates are lower. Even decapitated, the male's body can complete copulation: the brain inhibits mating reflexes, so removing the head actually accelerates sperm transfer. Egg cases (oothecae) are foam-like packets cemented to twigs in autumn that overwinter and hatch hundreds of nymphs in spring.
