Mantis key facts

Care level

Beginner-friendly

Lifespan

Adult 3-6 months

Size

40-100mm

Diet

Insects (Crickets etc.)

Housing

Tall case to secure molting space

Breeding

Female may eat male after mating

Notes

Failed molt is biggest risk. Humidity management key

Temperature & Humidity

It does best at 20-28°C. Use a well-ventilated plastic case to prevent stuffiness, and mist lightly before molts.

Diet & Feeding

Feed live crickets, dubia roaches, or grasshoppers. As an ambush predator, it rarely responds to food that does not move.

Breeding & Egg-laying

It lays many eggs in a foamy case called an ootheca, and many nymphs hatch in spring. Separate them early after hatching to prevent cannibalism.

About Mantis

Mantises belong to a diverse order of approximately 2,400 species worldwide, with several native species such as the Chinese mantis and wide-abdomen mantis found across Japan. Their iconic sickle-like forelegs are finely tuned predatory tools capable of snatching prey with remarkable precision. The triangular head rotates freely, giving mantises a wide field of vision, and their compound eyes provide sharp depth perception that aids in targeting fast-moving insects. Temperament varies by individual, but mantises are generally solitary and territorial by nature. As pets, their greatest appeal lies in witnessing live hunts: the patient stillness followed by a lightning strike is endlessly compelling to watch. Enclosures and equipment are inexpensive and simple to set up, making mantises an accessible entry point into insect keeping for both children and adults alike.

7 things to know before welcoming a Mantis

1. 1Vertical Space Is Essential

   Mantises need to hang from the top of their enclosure during molting, so the cage height should be at least three times their body length. A mesh-lidded vertical terrarium is the standard choice. Good ventilation also prevents mold and excess humidity.

2. 2Temperature and Humidity

   For Japanese native species, aim for 25–30°C and 50–70% humidity. Overly dry conditions can lead to molting failures, so lightly mist the cage walls. A small panel heater helps maintain warmth in winter.

3. 3Always House Alone

   Mantises are highly cannibalistic and will prey on each other regardless of size. Always keep one per enclosure. Even for breeding purposes, place them together only briefly under close supervision and separate immediately afterward.

4. 4Live Prey Is the Staple Diet

   Live insects such as crickets, fruit flies, and mealworms form the core diet. Offer prey no wider than the mantis's head. Remove uneaten feeders promptly, and withhold food for 24 hours before and after molting.

5. 5Watch for Molting Problems

   Molting failures are a common cause of death, often due to low humidity, poor nutrition, or insufficient cage height. Never handle or feed a mantis during molting. Allow 1–2 days for the new exoskeleton to harden before resuming normal care.

6. 6Short Lifespan to Expect

   Adult mantises typically live only 3–6 months and rarely survive winter. Starting from an egg case (ootheca) lets you observe the full life cycle from hatching to adulthood. Commit to caring for them for their entire lifespan before acquiring one.

7. 7Handle With Care

   Mantises stress easily when handled and may adopt a threat display or attempt to flee when startled. Some individuals become comfortable perching on a hand over time, but never force contact—introduce handling gradually by reading the mantis's body language. Their forelegs can cause minor scratches.

Frequently asked questions about Mantis

Q.Are mantises suitable for beginners?

A.Mantises are generally manageable for beginners. The main challenges are sourcing live prey consistently and monitoring molts, so starting with a domestic species nymph is recommended for first-time keepers.

Q.Do mantises need to be fed every day?

A.Daily feeding is not necessary; two to three times per week is a typical schedule. Observe your mantis's appetite and adjust accordingly. It is normal for mantises to stop eating before a molt, so do not force-feed during this period.

Q.Can I keep multiple mantises together?

A.Co-housing mantises is not recommended due to their cannibalistic nature. Even similarly sized individuals may attack each other, so each mantis should be kept in its own separate enclosure at all times.

Q.Can I raise mantises from an egg case?

A.Hatching mantises from an ootheca is possible, but be aware that dozens to over a hundred nymphs may emerge at once. Securing enough space and live food for all of them can be challenging, so plan for rehoming surplus nymphs in advance.

Q.How do mantises survive winter?

A.Wild domestic mantis species do not survive winter as adults; they overwinter as eggs in an ootheca. Pet adults kept indoors can live out their natural lifespan in a heated room, though activity slows in cooler temperatures. Monitor behavior and adjust feeding frequency accordingly during colder months.
