Praying Mantis
Invertebrates
Nature's most impressive ambush predator, in a palm-sized package!
🤓 Did you know? Praying mantises are the only insects known to have a single ear, located in the center of their chest between their hind legs. They use it to detect the ultrasonic calls of hunting bats, letting them dodge mid-flight. They are also the only insect that can turn its head 180 degrees.

🏠 Housing & Setup
Most pet mantis species (Ghost Mantis, Chinese Mantis, African Flower Mantis) need a small vertical enclosure. A tall deli cup (for nymphs) to a 12x12x18 inch mesh or acrylic enclosure (for adults) is appropriate. The rule of thumb is 3 times the mantis length in height and 2 times in width. Cross-ventilation is critical. Mantises molt hanging from the top of the enclosure so adequate height is non-negotiable. Provide a stick or branch angled from floor to ceiling for perching and molting. Temperature ranges from 72 to 95 degrees F depending on species. Most common pet species do well at 75 to 85 degrees F.
🥗 Diet & Feeding
Mantises eat live prey exclusively. Match the prey size to the mantis: fruit flies (Drosophila melanogaster, the small species) for early nymph stages, progressing to bottle flies, small crickets, and small dubia roaches as the mantis grows. Adult mantises can handle larger crickets, mealworms, waxworms, and bottle flies. Prey should never exceed the space between the mantis's eyes in width.
Feed every 2 to 3 days. Mantises will fast in the days before molting - do not offer prey during this time and remove any uneaten insects promptly. After molting, wait until the mantis's legs and mouthparts are fully hardened (several hours to a day) before offering food. Adult females require more frequent feeding than males and have significantly longer lifespans.
Prey variety is beneficial. Waxworms are high in fat and should be treats rather than staples. Bottle flies (blue or green bottle flies in pupae form, which you hatch at home) are one of the best feeders for many mantis species - appropriately sized, easy to culture, and eagerly taken.
🎮 Enrichment & Handling
Mantises are highly visual, active hunters that track and stalk prey with their distinctive head-turning behavior. Watching a mantis hunt - the slow, swaying approach followed by a lightning-fast strike - is one of the most captivating behaviors in the invertebrate hobby. The prey of the day (and the hunting sequence) is the primary enrichment.
Provide varied perching structures at different heights: branches, cork bark, artificial plants, and vertical surfaces. Mantises naturally vary their position throughout the day. Some docile species (Orchid Mantis, African Flower Mantis) can be gently handled - allow them to walk voluntarily from hand to hand. They may bite if startled or if fingers smell like prey.
Their "alien" compound eyes, remarkable camouflage, and astonishing hunting behaviors make mantises among the most visually engaging invertebrate pets. They are genuinely fascinating display animals.
💊 Health & Common Issues
Failed molts are the primary cause of mantis death in captivity. The mantis hangs upside down from the enclosure top to molt, pulling free of its old exoskeleton. If the enclosure is too short, too humid, too dry, or if the mantis is disturbed during this process, the molt fails and the mantis dies or is permanently injured. Always ensure adequate height (3 times the mantis length minimum) and an appropriate perch from which to hang.
Maintain appropriate humidity for the species by misting one side of the enclosure once daily. Dehydration causes failed molts. Overcrowding and cannibalism are serious risks - always house mantises individually, one per enclosure. Even a mantis kept alone for weeks has been known to cannibalize a newly housed enclosure mate.
Most pet mantis species have lifespans of 12 to 18 months. The hobby cycle for mantises is acquisition as a nymph, raising through multiple molts to adulthood, and a relatively short adult phase. Females live significantly longer than males.

❓ Frequently Asked Questions
How long do praying mantises live?
Most pet species live 12 to 18 months total. Females live significantly longer than males - males often die shortly after their final molt to adulthood, while females continue living and laying eggs for months. The typical keeper experience is acquiring a nymph, raising it through 6 to 9 molts over several months, enjoying the adult phase, and then the cycle ends. If you want continuous mantis keeping, plan to culture your own oothecae (egg cases) or establish a reliable supplier for juveniles.
Can praying mantises be kept together?
Never. Praying mantises are solitary, highly territorial, and cannibalistic with any insect they can catch - including a sibling they have lived next to for weeks. Even a mantis kept in complete isolation for months will immediately attempt to eat a newly introduced individual. Always house one per enclosure, no exceptions. The only intended exception is brief supervised mating, and even then the female frequently eats the male during or after the process.
What do praying mantises eat?
Live prey exclusively, sized to the mantis. Early nymphs eat fruit flies (Drosophila melanogaster). As they grow, progress to bottle flies, small crickets, and appropriately sized dubia roaches. Adults can handle larger crickets, mealworms, waxworms, and bottle flies. Prey should never exceed the space between the mantis's eyes in width. Feed every 2 to 3 days and always remove uneaten prey promptly - stress from live prey in the enclosure can interfere with molting.
What causes failed molts in mantises?
The top three causes are: enclosure too short (the mantis needs 3x its body length in height to hang and pull free of the old exoskeleton), humidity too low (dry conditions make the old skin brittle and hard to exit), and being disturbed during the molt. Never handle, disturb, or offer food when a mantis is hanging still from the cage top - this is pre-molt positioning. A mantis that gets stuck in a molt almost always dies. Prevention is the only viable approach.
Can praying mantises be handled?
Many docile species tolerate gentle handling well - Ghost Mantis, African Flower Mantis, and Chinese Mantis are commonly reported as calm on the hand. They may bite if startled or if fingers smell like prey (from handling insects), but the bite of most pet mantises is minor - more surprise than damage. Always let the mantis walk voluntarily onto your hand rather than grabbing it. Some individuals are more defensive than others; read the individual animal's posture before attempting contact.
