“Praying mantises are the only insects that can turn their heads a full 180 degrees to look behind them!”
European mantises are patient ambush predators of warm grasslands, gardens, and scrub. A mobile triangular head tracks nearby movement, while folded, spine-lined forelegs snap forward to seize flies, crickets, moths, and other insects.

A closer look at habitat, diet, behavior, reproduction, and conservation.
Praying mantises are predatory insects with an elongated prothorax and spined front legs folded in a prayer-like position. They use camouflage, binocular vision, and rapid foreleg strikes to capture prey in temperate and tropical habitats.
Adult mantises vary widely by species, generally 5 to 8 centimeters and 1 to 5 grams. The signature feature is the raptorial forelegs: massively enlarged, armed with rows of interlocking razor spines, and able to shoot out and snap shut faster than the eye can follow, pinning prey like a spiked bear trap. Vision is central to their hunting: a mobile, triangular head can swivel a full 180 degrees — unique among insects — and two big compound eyes set on the upper corners give wide binocular vision for judging strike distance, backed by three simple eyes (ocelli) sensitive to light changes. Many species are winged, and males often fly at night to find mates; to dodge echolocating bats, many carry a single ear on the underside of the thorax that detects ultrasound and triggers an evasive dive. It is the defining member of the order Mantodea, with over 2,400 species, the largest family being Mantidae; the lineage split from the ancestor of cockroaches and termites over 100 million years ago.
Praying mantises have a nearly cosmopolitan distribution across Europe, Asia, Africa, and North America, thriving anywhere vegetation supports enough insect prey — temperate and tropical grasslands, shrubland, meadows, farm fields, and forest canopy. Habitat choice is bound to camouflage (crypsis): a green mantis positions itself among fresh foliage, a brown one among dry twigs, dead leaves, or bark, integrating so completely into its surroundings that neither prey nor predator detects it.
The praying mantis is a strict carnivore with a ravenous appetite, feeding mainly on other arthropods — flies, crickets, moths, grasshoppers, caterpillars, and pollinators like bees and wasps — while large species have been recorded taking small vertebrates: tree frogs, small lizards, mice, even hummingbirds. It hunts almost entirely by sit-and-wait ambush, holding still for hours on a stem or flower (some species sway to mimic a leaf in the wind), then executing its lightning strike. It uses no venom, relying on sheer mechanical force to hold prey in the spiked vice, and begins eating immediately — usually head-first — shearing through exoskeleton with powerful mandibles so the prey can't escape or injure it.
Mantises are fiercely solitary throughout life, with no colony structure or parental care beyond egg-laying, and encounters between individuals often end in cannibalism regardless of other food. Their behavior is driven by hunting, avoiding predators, and mating; they are territorial over ambush sites and repel intruders. Threatened by a bird, lizard, spider, or frog, a mantis may drop its camouflage for a dramatic deimatic (startle) display — rearing up, fanning its wings to look bigger, raising the spiked forelegs, and flashing hidden eyespots, sometimes with a hiss of air from the abdomen.
Some mantis species show sexual cannibalism, in which a female eats the male during or after mating, but its frequency varies by species and conditions. The female produces an ootheca, a protein case containing 100 to 300 eggs that hardens on a twig and protects the eggs through winter. In spring, wingless nymphs hatch, disperse, feed, and pass through several molts before reaching winged adulthood. Many temperate species complete the life cycle within a year.
The common praying mantis (Mantis religiosa) and most widespread species are Least Concern with stable populations, buffered by high reproductive output and adaptability to gardens and farmland. They aren't immune to pressure, though: they face heavy natural predation from birds, bats, and larger arthropods, and the biggest human threat is broad-spectrum pesticides, which kill mantises directly and wipe out their insect prey, while habitat clearing removes ambush sites and overwintering spots for oothecae.

Praying mantises are the only insects that can turn their heads a full 180 degrees to look behind them!
Their front legs are armed with sharp spikes that lock prey into place so they cannot escape.
A mantis has a single ear located on the underside of its belly, which it uses to detect the ultrasound of hunting bats.
They are masters of disguise, mimicking green leaves, dry brown twigs, or even flowers to hide from predators.
A female mantis lays her eggs in a frothy foam that hardens into a tough paper-like case called an ootheca.
Praying mantises have 5 eyes: two large compound eyes on the sides and three tiny simple eyes in the middle of their head.
Select a question to reveal the answer.
Praying mantises live in warm regions worldwide, including Europe, Asia, Africa, and North America. They are commonly found in gardens, meadows, grasslands, and forests, hiding on green leaves or brown twigs.
Praying mantises are carnivores that eat other insects such as flies, crickets, grasshoppers, moths, and bees. Larger mantises have even been known to catch tiny frogs, lizards, or hummingbirds!
They hold their folded front legs in a posture that looks like praying, but those legs are built for grabbing prey.
Some adult mantises can fly, especially males, but flight ability varies by species and sex.
They can eat pest insects, but they also catch beneficial insects, so they are general predators rather than targeted pest control.
