A large, hardy mantis originally from Asia and now widely established across the US, making it a popular and forgiving beginner mantid. Like all mantises it lives roughly a year, with adults surviving only a few months after the final molt.

Part of the Mantises
Praying mantises — solitary, cannibalistic ambush predators kept individually in tall, well-ventilated enclosures with climbing decor. They need vertical headroom for safe molting, live insect prey, and gentle misting; most are harmless and many tolerate light handling.
From the minimum an animal needs to be kept humanely, up to the ideal setup. Bigger is almost always better — minimums are floors, not targets.

Life & growth stages
How this animal changes through its life — each stage often has its own care, diet and space needs.

Egg
Insects begin as eggs, laid singly or in clusters on or near a food source. Egg size, shape, and incubation time vary widely; some are glued to surfaces, others inserted into plant tissue or soil.

Larva / Nymph
The immature stage either looks grub- or caterpillar-like and very different from the adult (a larva, in beetles, flies, and butterflies) or like a wingless miniature adult (a nymph, in roaches, mantises, and stick insects). It eats and molts repeatedly as it grows.

Pupa
In insects with complete metamorphosis, the larva pupates — often in a cocoon, chrysalis, or sealed cell — and its body is reorganized into the adult form. Nymph-developing insects skip a true pupa and molt straight to the adult.
Adult
The adult is the sexually mature, usually winged stage with the species' full coloration and form. Adults are typically the dispersing and reproducing stage, and in many insects do not grow further once mature.
Habitat & enclosure
House singly in a tall enclosure at least 3x the mantis's length in height (a 30x30x45 cm / ~12-18 in tall mesh or glass terrarium suits an adult), giving vertical space to hang and molt. Provide twigs, branches, and artificial or live foliage to climb and anchor to. Keep at 22-28 C (72-82 F) with moderate humidity (~50-60%), achieved by light misting. Adequate vertical clearance below a secure perch is critical for safe molting.
Substrate
A simple substrate of coco fiber, paper towel, or a thin soil layer that holds a little humidity and is easy to keep clean; depth is unimportant since mantises live on vertical surfaces rather than burrowing.
Equipment & setup
Tall, well-ventilated enclosure (mesh sides aid grip and ventilation), perching twigs/branches reaching near the top, a spray bottle for misting, and a thermometer/hygrometer. Heating is rarely needed at normal room temperature; a low-wattage heat source on a thermostat helps in cool homes. No UVB required.
Diet
An aggressive generalist predator. Feed live, appropriately sized insects — fruit flies for tiny nymphs, graduating to houseflies, crickets, roaches, and moths for adults. Feed nymphs daily/every other day and adults every 2-4 days, removing uneaten prey. Mist for drinking water; mantises drink droplets from surfaces.
Behavior & temperament
Bold and visually engaging; a classic ambush predator that grabs prey with its raptorial forelegs. Generally calm and among the more handleable insects, though it may grasp a finger or give a harmless pinch — handle low over a soft surface. Solitary and strongly cannibalistic, so house individually except for brief, supervised, well-fed breeding attempts. Note: as a non-native, established species in the US, mantises should never be released.
Health
Hardy but bound by a fixed roughly one-year lifespan. The most common keeper-caused deaths are mismolts (from insufficient vertical space, low humidity, or disturbance during molting) — never feed or handle a mantis that is preparing to molt or hanging upside down. Other issues include dehydration (mist regularly) and impaction or gut problems from oversized or contaminated prey. Provide cleanly raised feeders.
Tips, DIY & hacks
Always provide a vertical perch with at least twice the mantis's body length of clear space beneath it for molting. Watch for pre-molt signs (refusing food, hanging still) and leave the animal undisturbed. Match feeder size to the mantis (no larger than roughly its head) and feed live prey. Because it is established/invasive in North America, never release it outdoors.
