Overview

The mantis is any member of the insect order Mantodea. Commonly called praying mantids or praying mantises because of their folded, prayer-like forelegs, they are predatory insects in the larger grouping of insects. The order contains roughly 2,300 described species found across temperate and tropical habitats. Many species belong to the family Mantidae and are referred to simply as mantids.

Anatomy and behaviour

Mantids are easily recognized by a suite of features adapted to an ambush-predator lifestyle: a triangular head with large compound eyes capable of stereoscopic vision, a flexible neck that allows substantial head rotation, and highly specialised raptorial forelegs armed with spines for seizing prey. Most adults have two pairs of wings, though some species are flightless. Their coloration and body shapes often provide excellent camouflage among leaves, bark, or flowers.

Life cycle, diet and ecology

Mantids undergo incomplete metamorphosis (hemimetabolous development): eggs are deposited in foamy masses called oothecae, nymphs hatch resembling small adults and grow through successive moults. They are predominantly insectivorous—feeding on flies, moths, and other arthropods—and larger species may capture small vertebrates. Their sit-and-wait predation, quick strike with forelegs, and occasional intra-specific aggression (including sexual cannibalism in some contexts) are well documented.

Distribution, relatives and distinctions

Species of mantids occur worldwide in suitable climates. In Europe the common phrase “praying mantis” usually denotes a single species, Mantis religiosa. Mantids can be mistaken for stick insects (phasmids, stick insects) but differ markedly in head mobility and foreleg structure. Phylogenetically, mantids are most closely related to cockroaches and termites (order Blattodea), and these groups together form the superorder Dictyoptera, with termites sometimes placed within Blattodea; the social termites are referred to separately as termites.

Human interactions and notable facts

  • Mantids are valued as natural pest controllers in gardens and occasionally kept as pets or display animals.
  • They are subjects of scientific study for vision, predation, and locomotion because of their binocular sight and rapid targeting behaviour.
  • Culturally, mantids have appeared in folklore and art as symbols of patience, stillness, or hunting skill.

Although diverse and ecologically important, many mantid species remain understudied; ongoing taxonomy and field research continue to refine their classification, distribution, and natural history.
