Do Praying Mantis Make Good Pets?
Praying mantis are brilliant, inexpensive pets for invert-lovers, or for people that want to try out something a little different. There are numerous species to choose from, varying widely in appearance and personality. Praying mantis are slow-moving and enjoy being handled. They are perfectly safe to keep and only attack insects.
Are Praying Mantis Easy To Care For?
Absolutely! Praying mantis are easy, low maintenance pets. They can live in a small glass or plastic enclosure, which can be bought online or made at home. A daily spray will keep them humid and hydrated, along with live food every couple of days. Fruit flies are brilliant for mantis nymphs, and as they grow, you can try out different feeders and see what works best for you. Praying mantis do not need cleaning out, and adults can even be kept free-roaming on houseplants.
How Long Do Praying Mantis Live For?
Praying mantis can live anywhere from just a few months to up to a rumoured two years, depending on both their species and sex. Praying mantis are only a short-term commitment as pets, and their short lifespan allows keepers to experience owning many new and exciting mantis species in the hobby.
Which Praying Mantis Species Should I Get?
There are numerous species of praying mantis all with their own care requirements. Species from hot, tropical countries are more likely to be considered “advanced” species, as they require high temperature and humidity levels. Beginner species are hardy and can thrive in cooler, less humid environments.
Later on, we’ll discuss the best and most popular species for beginners.
Praying Mantis Care
Before we get into this section, you should know that praying mantis care heavily varies by species.
For example, different praying mantis species may require different humidity and temperature levels. Species marked as “beginner” in our store generally have low humidity & temperature requirements along with simple care needs.
It’s important that, as a new keeper, you research the mantis you want to purchase beforehand, and make the responsible choice based on what is right for you. To supplement our care guides, we have numerous detailed articles on sexing, feeding, molting, health issues, and more on our care guides page to ensure you have all the information you’ll need.
Mantis keeping is a simple learning curve, however it’s always recommended to start with a beginner friendly species first before owning advanced species.
Molting In Praying Mantis
This is an important section to talk about first as most aspects of praying mantis care revolve around ensuring successful molts. For a more in-depth look into molting, mismolts, instars and more, check out the article linked below.
Molting is a vital process in the lifecycle of all arthropods that allows them to grow. Arthropods, including insects and arachnids, have a hard, protective exoskeleton.
This sturdy exoskeleton keeps the animal safe but is so strong and inflexible that they cannot grow larger within it. So, in order to grow and mature, they must break out of it. This process of removing & creating a new exoskeleton is called molting.
Praying mantis molt around 6-10 times before reaching adulthood, depending on species and sex. As young nymphs, you should expect around a couple of weeks interval between molts. Older mantis may take a month or more.

Removing the exoskeleton is a taxing process that relies on internal secretions and external humidity levels to soften the external skin. For this reason, your mantis will be soft and vulnerable during and shortly after a moult.
The new, fresh exoskeleton will harden over hours or days as it returns to its strong, defensive state. This process is called hardening.
You should never handle your mantis during this process – wait at least 48 hours until they have fully hardened. It’s safe to handle your mantis when they start accepting food again.
Unfortunately, complications can occur during moults that result in deformities. Praying mantis can involuntarily fall while shedding their exoskeleton and harden into a deformed position. Mismolts are often fatal, but mild deformities and missing limbs can be regenerated in the next moult. You can learn about mismolts and how to deal with them in our guides on molting and health issues.
The Instar System
The instar system is a system used for ageing both insects and arthropods as they molt. After leaving the ootheca, (the mantis egg case) praying mantis nymphs are first classed as L1, the first instar. After molting, they become L2, second instar. Next, L3, third instar, and so on until adulthood.
Most praying mantis nymphs are sold as L2.
The number of molts a mantis will have depends on the species and sex. On average, praying mantis molt around 6-10 times before becoming adults.
Mantises mature after their final moult, marked by the development of wings. After breaking free of their exoskeleton, praying mantis hang upside down and pump blood through crumpled wing buds to inflate them.
The term “sub-adult” refers to mantis just one instar away from adulthood. Sub-adult mantis have large, swollen wing buds that look like little backpacks.
Wing buds become plump, and even change colour as the final molt approaches, until finally freed from the exoskeleton where they sprout into wings.
Feeding Your Mantis
For information on the best feeders to use as your mantis grows, check out our complete feeding guide.
Praying mantids are largely insectivorous predators. In the wild, the diet of a mantis consists primarily of flying pollinators and pests, although they seem to enjoy eating almost anything. Some species have a preference for flying insects which can be easily catered to.
For young l2 nymphs of almost every species, we recommend fruit flies.
Praying mantis species are all different sizes and prefer different foods, so our general advice is to offer food around a third of your mantids total body size as it grows. Some species may prefer smaller or larger prey, so it’s best to do your research on whichever species you own or are looking to get.
2. How Do I Feed My Mantis?
The simplest way to feed your nymph is to place fruit flies into their enclosure. There are a couple of things to look out for, however.
Certain feeder insects may nibble or hurt your mantis when they are vulnerable mid-molt, such as crickets. It’s important to never leave feeder insects in your tank for a long time – if your mantis has not eaten its food after several hours, try again another day.
This is not generally an issue with fruit flies, however their flighty behaviour can be a disturbance to praying mantis in pre-molt.
While you should feed your mantis every several days or so, praying mantis can live up to 2 weeks without eating. You can easily tell when a mantis is full by the size of its abdomen – a flat abdomen shows feeding is due, a plump abdomen shows it is well fed, as seen below.
Housing & Enclosures
It’s surprisingly simple to create a mantis enclosure, but beginners often make some easily avoidable mistakes.
For a detailed look at choosing, decorating, or creating an enclosure, check out our guide linked below.
There are plenty of suitable options for enclosures around.
Some of our favourites include pop-up mesh enclosures, exo-terra glass vivariums, and “Bug Pets Made-For-Mantis” enclosures. When purchasing an enclosure, its crucial for it to have some sort of mesh top (preferable plastic or fabric) and suitable airflow from holes or mesh as these features both prevent mismolts and encourage the removal of stale air, which reduces the chance of mould and bacterial infections.
Nymphs can be housed quality enclosures, or in small deli-cups or other repurposed containers given you’re following the guidance mentioned above.
The Bug Pets Made-For-Mantis enclosures are designed to be an affordable option for all beginner and intermediate mantis species to ensure the best keeping conditions, and to take the hassle out of choosing a mantis enclosure. Enclosures on the market are often made for other animals or won’t necessarily the best option for beginner species.
Decorate your praying mantis enclosure with sticks, bark, live plants, soil or coco coir substrate. Avoid sharp twigs, sharp rocks, crystals, spikey plants, and other objects your mantis may hurt itself on.
All praying mantis need certain temperature and humidity levels that reflect their natural environment. Beginner species are less demanding, where advanced species prefer it to be warm and humid. Hygrometer-thermometers can be purchased in our store or on various other stores online.
The RH (relative humidity) for a particular species can be found in our care guides page, or in the shop page for that species.
Misting the enclosure walls and decor every day allows your mantis a drink and boosts the humidity, along with moistening the substrate. It goes without saying that the more ventilation your enclosure has, the more spraying it will need to stay humid.
If you live in a colder home and need to keep the temperature up, use a heat mat.
Sexing Your Mantis - Male Or Female?
Sexing praying mantis can be a little complicated for new keepers. We’ll go over it briefly here, however we discuss it in more detail in our sexing article.
Different praying mantis species present their sexual dimorphism (anatomy exclusive to either males or females) in different ways, but the most universal way to sex a mantis is by looking at their size, as female praying mantis are almost always larger than males. As adults, size is a simple way to sex many species, however it can be difficult to tell in small growing nymphs.

As we’ve just mentioned, however, sexual dimorphism in some mantis species can be different or greater than others. Here’s an example of sexual dimorphism in the Orchid mantis, using a coin for scale.

As you can see, the size difference and general anatomy is much more exaggerated than in the giant Asian mantis. You might not even realise they’re same species at first glance.
Another popular method of sexing mantis is to count their abdominal segments. Males typically have more segments than females, while females have less. Once again, we cover this in great detail in our guide to sexing linked at the top of this section, along with a breakdown of sex-based anatomical differences.
The Best Beginner Mantis Species
If you’re new to mantis keeping, we recommend you start with a beginner species. Good beginner mantis species include:
The majority of new keepers start out with either the ghost mantis or giant Asian mantis. We recommend the giant Asian mantis, African mantis, budwing mantis, and Madagascan marbled mantis most of all to new keepers. If you’d prefer a more unique species, we recommend the ghost mantis or spiny flower. If you’re looking for a big species, a better choice may be the giant Asian. If you’re looking for aggression, the giant African mantis is perfect.
Giant Asian Mantis
Giant Asian mantis are a brilliant beginners choice due to their large size and huge appetite. H. Membranacea mantis are notorious gluttons. Hierodula Membranacea grow to around 4 inches long and are low maintenance, hardy pets. This is our top beginners recommendation.
Ghost mantis are a strikingly unique species popular for their ease of care and distinctive appearance. While ghost mantis do not have difficult environmental needs, they are a timid species that often become scared of their own food. Ghost mantis are not flighty, however, quite the opposite. They stay very still on your hand, and even play dead. Ghost mantis are so timid, they can even be kept communally as they are unlikely to eat one another.
Spiny Flower Mantis
The spiny flower mantis, Pseudocreobotra wahlbergii, is a stunning species of flower mantis native to eastern Africa. Due to its natural arid habitat, the spiny flower mantis does not have exceptionally difficult environmental care requirements like high humidity for keepers to deal with. This makes P. wahlbergii a unique choice for inexperienced keepers. And, if you’re not already convinced by its simple care needs, just take a look at its stunning wings.
Giant African Mantis
Just a little smaller than the giant Asian mantis, the giant African mantis packs infinitely more punch. These are, without a doubt, the feistiest mantis we have owned. If you’re looking for a truly aggressive mantis, Sphodromantis sp. is absolutely the choice for you. They make little distinction between food and fingers (as we have regrettably found) and are extreme gluttons. The giant African mantis is hardy and great for beginners if you can handle them calmly and deal with having your fingers munched every once in a while.
