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. Short Lifespan to Expect

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.
