Stick Insect vs Praying Mantis for Kids
Stick insects and praying mantises can both disappear against leaves and twigs, but they belong to different insect orders and live opposite feeding lives. This page uses the giant prickly stick insect, Extatosoma tiaratum, and European mantis, Mantis religiosa. The stick insect is a slow leaf-eating phasmid that survives by looking and moving like vegetation. The mantis is a predatory mantid that uses camouflage to bring other insects within reach of spiny grasping forelegs.
Giant Prickly Stick Insect
- Type: Large Plant-Mimicking Stick Insect
- Group: Living species Extatosoma tiaratum in order Phasmatodea, also called the spiny leaf insect or Macleay’s spectre
- Known for: Large wingless spiny females, flying slender males, curled leaf-like body, eucalyptus diet, night activity, wind-matched swaying, seed-like eggs carried by ants, ant-mimicking hatchlings, and parthenogenesis
- Diet: Herbivore eating eucalyptus and other suitable leaves
- Special skill: Resembling a thorny dead leaf in shape, colour, posture, and wind-timed swaying while dropping seed-like eggs that ants may carry underground
European Mantis
- Type: Camouflaged Raptorial Praying Mantid
- Group: Living species Mantis religiosa in order Mantodea, used as a precise praying-mantis benchmark
- Known for: Triangular mobile head, large compound eyes, binocular depth judging, long neck-like prothorax, folded spiny raptorial forelegs, fast adjustable prey strike, green or brown camouflage, wings, foam egg case, and one midline ultrasonic ear
- Diet: Carnivore eating insects and other small arthropods caught by ambush
- Special skill: Judging prey distance with widely spaced eyes, rotating a triangular head, and adjusting a rapid two-foreleg strike even after the strike has begun
Quick Answer
Quick answer: A giant prickly stick insect is a herbivore in order Phasmatodea. Large females can approach 20 centimetres and resemble curled thorny leaves; they sway with wind, drop seed-like eggs, and can reproduce without a male. A European mantis is a smaller carnivore in order Mantodea, usually about 5-7.5 centimetres long, with a mobile triangular head, binocular eyes, one underside ear, and spiny folding forelegs that launch a rapid prey-capture strike.
Giant Prickly Stick Insect vs European Mantis: Quick Comparison
| Feature | Giant Prickly Stick Insect | European Mantis |
|---|---|---|
| Scientific identity | Extatosoma tiaratum, order Phasmatodea | Mantis religiosa, order Mantodea |
| Adult length | Females can approach 20 centimetres; males are smaller | About 5-7.5 centimetres |
| Main diet | Leaves, especially eucalyptus | Insects and other small arthropods |
| Front legs | Walking and climbing legs without a prey trap | Enlarged folding raptorial legs lined with gripping spines |
| Head and vision | Small head with plant-matching outline and compound eyes | Mobile triangular head with large widely spaced eyes and binocular depth vision |
| Camouflage style | Looks like a thorny curled leaf and sways like wind-blown foliage | Green or brown body waits among matching leaves and stems |
| Adult wings | Slender males fly; heavy females have reduced non-flying wings | Both sexes have wings, though heavy females may fly poorly |
| Egg protection | Hard seed-like eggs dropped separately; ants may move them | Many eggs sealed together in a hardened foam ootheca |
| Newly hatched young | Fast black-and-orange nymph resembles a spider ant | Tiny mantis-shaped nymph resembles a wingless adult |
| Standout clue | Curled thorny leaf body with no grasping prey legs | Prayer-like spiny forelegs and a swivelling triangular head |
How Are Giant Prickly Stick Insect and European Mantis Alike?
- Both are six-legged insects with a head, thorax, abdomen, antennae, compound eyes, an external skeleton, and repeated moults while growing.
- Both use green or brown colours, stillness, plant-like outlines, and gentle swaying to reduce detection among vegetation.
- Both hatch as nymphs that resemble smaller wingless versions of the general adult body plan rather than worm-like larvae.
- Both show strong differences between adult males and females in size, body build, wings, flight, and reproductive behaviour.
- Both lay protected eggs on or near plants, but neither parent raises the hatchlings in a cooperative family group.
How Are Giant Prickly Stick Insect and European Mantis Different?
- The giant prickly stick insect is in order Phasmatodea, while the European mantis is in the separate order Mantodea.
- The stick insect eats leaves, while the mantis is a sit-and-wait predator of other arthropods.
- The stick insect’s ordinary front legs are built for climbing, while the mantis has enlarged spiny forelegs built to seize prey.
- A giant prickly female can approach 20 centimetres, while the European mantis is usually around 5-7.5 centimetres.
- The stick insect drops individual seed-like eggs that ants may collect, while the mantis seals many eggs inside one hardened foam case called an ootheca.
Stick Insect vs Praying Mantis Showdown
Adaptation showdown: Giant Prickly Stick Insect wins size because females can approach 20 centimetres, far beyond the European Mantis at roughly 5-7.5 centimetres. European Mantis wins speed only for the specialised prey strike, whose timing can be adjusted during motion; this is not a claim about running speed. European Mantis wins task-specific strength because enlarged spiny raptorial forelegs clamp prey, whereas stick-insect legs mainly climb and support camouflage. Stealth is a Tie because the stick insect’s leaf masquerade and wind-matched swaying solve a different problem from the mantis’s ambush camouflage. Social behaviour is a Tie because both are mainly solitary. Swimming is a Tie because neither is aquatic and no meaningful matched test exists. Giant Prickly Stick Insect wins weirdest for combining seed-like ant-carried eggs, ant-mimicking hatchlings, wind-matched swaying, parthenogenesis, large wingless females, and flying males.
Fun Stick Insect vs Praying Mantis Facts
They Are Not Two Versions of One Insect
Stick insects belong to Phasmatodea, while praying mantids belong to Mantodea. Both sit within a broader branch of insects that undergo incomplete metamorphosis, but their specialised body plans and diets evolved along separate lines.
The Stick Insect Is the Plant Eater
Giant prickly stick insects chew eucalyptus and other suitable leaves. Their mouthparts, legs, camouflage, night activity, and slow movement support a life spent feeding without attracting predators. A European mantis instead eats animals it can grasp.
Its Swaying Really Matches Moving Plants
Researchers filmed adult female E. tiaratum in three dimensions. Wind triggered swaying, and the movement frequency overlapped with wind-blown plants, supporting a possible motion-crypsis or motion-masquerade function.
Ants Can Become Accidental Egg Couriers
Each hard stick-insect egg has an edible knob called a capitulum. Some ants carry the seed-like egg into a nest, remove the knob, and leave the viable egg protected; the fast hatchling then resembles a black-and-orange spider ant.
A Praying Mantis Has One Central Ear
The European mantis has a single auditory organ on the underside midline of its rear thorax rather than a left-right ear pair. It is especially sensitive to ultrasound, including frequencies used by hunting bats during flight.
Stick Insect vs Praying Mantis Quiz
- Which insect can approach 20 centimetres? Answer: The female giant prickly stick insect.
- Which insect is the herbivore? Answer: The giant prickly stick insect.
- What are the mantis’s prey-catching legs called? Answer: Raptorial forelegs.
- What is a mantis egg case called? Answer: An ootheca.
- Where is the European mantis’s single ear? Answer: On the underside midline of the rear thorax.
Stick Insect vs Praying Mantis FAQ
Are stick insects and praying mantises the same kind of insect?
No. Stick insects are in order Phasmatodea, while praying mantises are in order Mantodea.
Which is bigger, a giant prickly stick insect or European mantis?
The giant prickly stick insect. Large females can approach 20 centimetres, while European mantises are roughly 5-7.5 centimetres.
Does a stick insect eat other insects?
The giant prickly stick insect is a herbivore that eats leaves. The European mantis is the predatory insect in this comparison.
Why do both insects sway?
Swaying can help them resemble vegetation moving in wind. The stick insect’s movement has been measured and shown to overlap with wind-blown plant motion.
Does every female praying mantis eat its mate?
No. Sexual cannibalism can occur, especially under some conditions, but it is not automatic at every mating and should not define all mantis behaviour.
