Praying mantes are carnivores and cannibals. They are voracious eaters of small bugs such as cockroaches, fruit flies, and house crickets. But they will devour each other if they don’t have anything else to eat.
The most common feeder insects for mantids are house crickets, cockroaches, and fruit flies. But they will also eat other small bugs such as worms, grasshoppers, spiders, bees, and wasps. Large mantids are also known to eat hummingbirds, frogs, lizards, and mice.
Mantis requires their prey to live in order to thrive. To eat live prey, mantis stalks them and strikes when the right time comes.
1. House Crickets
House crickets are the most common feeder for Mantids. These insects are nutritious, and they catch mantids’ attention.
They are also inexpensive and easily accessible. Pet stores are the best places to purchase these feeder insects.

2. Fruit Flies
Mantids love fruit flies. They are the best feeder for most mantids in their primary nymph growth. You can order these via mail without wings, although wingless fruit flies tend to be more pricey.
In their second molt, mantids are typically ready for larger prey like cockroaches, firebrats, and tinier crickets.
Other types of flies mantids eat are House flies, Stable flies, Bluebottle flies, and Humpbacked flies.

3. Cockroaches
Cockroaches are an ideal meal for mantids, especially in their growing stages.
These insects are used by the most dedicated hobbyist. That’s because cockroaches come in all different sizes and species.
This is because cockroaches are easy to maintain. They don’t need water or food to keep alive. Roaches are also safe to live in mantid enclosures even when mantids are molting before they eat.

4. Larva
Mantis are voracious eaters of silkworms, waxworms, mealworms.
Mealworms are beetle larvae, and silkworms are moth pupae.
Both these bugs are ideal feeder insects for nymph mantids. They are easy for them to hunt but still allow the mantids to search and find them.
5. Hummingbirds
Large mantids are strong enough to catch and eat hummingbirds. This generally happens when the hummingbirds feed on hummingbird feeders.
Mantids tend to hide on hummingbird feeders and wait for hummingbirds or bees to approach. As they drink the sugar water, the praying mantis will attack them.
Once a mantis finds a bird feeder, they generally develop a fixation. They will come back repeatedly to hunt hummingbirds and bees.

6. Springtails
Springtails are another common feeder insect for mantis. These insects are generally found in plants, compost piles, and lawn soils.
They consume dead plants and are beneficial pests in gardens. Springtails are not dangerous. They don’t bite, spread disease, or damage properties.
7. Mantids
Mantis are cannibals. While they prefer to eat other prey, they’ll devour each other if they don’t have anything else to eat.
Mantids also engage in sexual cannibalism. That means females bite the head of males after mating. A common misconception is that they bite the head off with one bite. Instead, mantids will bite into their head until it completely removes it.
It’s important to note that this doesn’t always happen. Only certain species of mantis will cannibalize their mate. It’s sometimes recommended that you feed your female mantis properly to prevent it from eating males.
Unfortunately, this is not an effective solution. According to studies, female mantids only eat the male due to hunger at most 30% of the time. This means that approximately 70% of the time, female mantids kill males without eating them.
To keep mantids from eating each other, make sure to consider their aggression levels. Different species have different aggression levels. Sometimes, you can communally keep mantids together. However, there are other scenarios where the insects are too aggressive for this to work.

8. Lizards
Large praying mantids are also known to attack and feed on lizards. It’s also possible for smaller praying mantids to feed on small lizards such as the western fence gecko.
While many think that the lizards can defend themselves against praying mantis they are vulnerable to attacks.
One of the main reasons mantids tend to attack lizards is they commonly hide in similar locations in trees, or among vegetation.
When attacking lizards they have no issue breaking through their though the skin and using their pinchers to keep them in place.
Lizards that are hunters and more aggressive can typically protect themselves against a mantis. For example, mantids are often eaten by bearded dragons.

9. Frogs
Another unexpected food source for mantids is frogs. Large species of mantids can easily kill smaller species of frogs.
Most frogs can’t protect themselves against powerful and ferocious predators such as a mantid.
Large frogs or even tods are less susceptible to matids because of their size and tough skin.
Any frogs or toads that are small may be in danger if there is a mantid nearby.

What to Feed Your Pet Mantis?
The most common feeder insects for mantis are house crickets, cockroaches, and fruit flies. For optimal feeding, a prey that is one-third of the mantis’ size is ideal.
For the primary nymph growth stages, fruit flies are best for most mantids. During their second molt, you’d want to feed them larger prey like cockroaches, firebrats, and tinier crickets.
Cockroaches are most ideal in Mantis growing stages. The most dedicated hobbyist uses these insects because of their variety and versatility.
Another thing to consider when choosing what to feed your mantis is their species.
For instance, if you have a species of Mantids that prefer to be in high areas, then it’s probably a good idea to feed them insects that fly. For this, you’d want to steer clear of prey that likes to be on lower areas, such as crickets and mealworms.
Also, keep in mind that certain feeders are not ideal for the molting stage. Crickets, for instance, like to hide. They can pose a danger to nymphs by a surprise attack, biting them amid the molting process.
Further, remember to feed females extra food before they mate. Doing so will prevent them from eating the males right after mating.
For budget purposes and supply management, enthusiasts often grow their own feeding insects for mantids. However, if you choose to capture their food, make certain that the insects had no exposure to fertilizers or insecticides. These substances can be toxic to mantids.
Finally, steer clear of hand-feeding mantids for safety purposes.
How to Feed Your Mantis?
There are two key things when feeding your mantis.
- Proper enclosure
- Feeding holes that allows you to insert food with ease
A proper enclosure should allow you to contain, breed, and feed your mantis. The best way to feed your mantis is using feeding holes.
These feeding holes will allow you to insert your mantid food into the enclosure. After inserting the food, you should be able to plug the hole, preventing your mantis from getting out.
How Big Should Praying Mantis Prey Be?
Nymph praying mantis typically eat insects that are about ⅓ of their size. This is typically sufficient food to keep them satisfied, and they normally will not continue eating afterward.
For adult praying mantis, they can eat large amounts of insects. In the wild, praying mantis gorge on food. After gorging, they can survive up to six weeks without food.
When feeding adult praying mantis, the size of the prez is not particularly important. They will feed on cockroaches, crickets, and even another praying mantis if given a chance.
What Do Mantids Drink?
Hydration is critical for mantids. Mantids survive on water like most other animals and insects. However, they differ from household pets such as dogs and cats because they are unlikely to drink from a water bowl.
Mantids drink water droplets. They typically find these on the surface of soil or plants. If you have a pet mantid, you should make sure that there are enough moisture or water droplets for the mantid to drink. If you see these insects lapping up water drops during enclosure, this is a clear signal of dehydration.
How Do Mantids Eat?
The most common misconception is that mantids bite the head off their prey. While this is possible, they don’t bite the head off as a consistent method.
Mantids rely on their size, speed, and strength to feed on their prey. Remember that mantids lack venom to immobilize or kill their prey.
Mantids bite their prey and begin feeding on their prey as it’s alive.
Mantids Are Picky Eaters
A mantis is known for being a picky eater. Just ahead of the molting process, nymphs cease eating. Males generally ingest vegetables. However, females need extra food before they commence the mating sequence. This is to ensure the males don’t die in the middle of the process.
Not all mantids eat a ton. Some can safely last weeks forgoing food. As long as they don’t become lethargic, there’s no problem.
If you overfeed mantids, they can sadly become obese. This can lead to suffocation and harm, especially for females with abdomens that become enlarged.
Frequently Asked Questions (FAQ)
Are Mantids Carnivorous?
Yes. Mantids are Carnivorous and are exceptional hunters. They should not be confused for phasmids which are herbivores and resemble “walking sticks.”
Mantids consume all prey. They also drink liquid regularly.
Are Mantids Cannibals?
Yes. Mantids are cannibals. Some but not all species of mantis engage in sexual cannibalism. That is, after mating, the female will eat the head of the male mantid.
About 30% of the time, the female will eat the male. It’s also possible that the female will eat the male if it’s hungry.
If you don’t give them anything to eat, they’ll begin devouring each other.
Sexual cannibalism, that is, females eat the head of males after mating, is also very much present.
One way to prevent females from eating the male head, they need to be liberally fed ahead of the mating process. Unfortunately, this is not always effective, and you should determine the species of matid to determine if they have a tendency to engage in cannibalism.
How Long Do Praying Mantis Live?
Mantis lifespans vary depending on the specific species. With that said, males die before females. The smaller specimens also die before the larger ones.
On average, nymphs require four to six months to reach adulthood. After adulthood, they have about three to eight months left before they die.
To lengthen lifespan, Mantis needs fewer feeding sessions and cooler temperatures.
Why Won’t My Mantis Eat?
Mantids can stop eating for a variety of reasons.
A common reason is that they are about to molt. Nymphs cease eating prior to the molting process. Males generally ingest vegetables.
Also, not all mantis eat a ton. Some can go all 14 days without consuming any food whatsoever. Certain species are also less frequent eaters than others. As long as they don’t become lethargic, there’s no problem.
If you overfeed mantids, they can sadly become obese. This can lead to suffocation and harm, especially for females with abdomens that become enlarged.
However, in cases when adults are refusing food, another style of insect feeder may be the necessary solution. Females always consume more food than males.
Is There Any Way to Tell if a Mantis is Getting Ready to Molt?
Days ahead of the molting process, mantids will hang in cages upside down and cease eating altogether. Sometimes, the body will also become coated with white “wash” of sorts. Also, be prepared to see swollen wing buds ahead of molting.
Do Praying Mantids Bite?
Yes. Praying mantis can bite. But they generally won’t unless provoked. That said, their bites are pretty harmless. All mantis species are do not carry diseases and aren’t poisonous.
Praying mantis may latch onto your finger if they mistake it for food. If the mantis is of considerable size, the latching will create the sensation of pinpricking. In the most unusual cases, you could also see a blood droplet.
Because mantis almost never bite and are not poisonous, they are one of the safest pets to keep around.
How Can I Tell if My Mantis is Fully Grown?
Mantids that are completely grown have the wings which nymphs lack.
Size, however, is not a good indicator of maturity. While age does cause mantids to grow, some species never grow beyond 1 inch long. Then, you have other species that can get to as big as 4 inches long. Wings, rather than size, are the best indicators of maturity.
Can I Visually Tell if an Ootheca is Fertilized?
The short answer is no. An external look will not reveal whether an ootheca is set to hatch. Each ootheca should be regarded as though the arrival of nymphs is soon to come.
Ootheca will still be generated by females who have not mated. However, hatching will never happen. This risk is always present. That’s the case regardless of whether they’re gathered in the wild or if mantids generate ootheca.
Where should I keep my Mantids?
The right habitat for your mantid will allow for insect containment, breathing, and feeding.
This means that your habitat needs feeding holes (which can also be plugged). You also want to make sure that you don’t constantly have to take the lid on and off. Finally, make sure your mantid can see the food within your habitat, so they won’t starve.
How Do I Know If My Mantis is Dying?
Consistently not eating or moving are strong indicators of a mantis that is either sick or dying. Mantids that regularly remain still or hanging from the habitat’s top could also be getting ready to pass away.
How Does Praying Mantis Die?
Praying Mantis can die in a variety of ways, including:
- Falling prey to parasites
- Falling prey to small mammals, arthropods, birds, amphibians, or reptiles
- Infection via pathogens of the microbial, bacterial, viral, and fungal types
- Molting and development complications
- Obesity
- Suffocation
- Dehydration
- Starvation
- Toxic chemical absorption
- Old age
- Interactions with people
Molting and development complications
Do not pull on a mantis or otherwise interfere with the molting process, even if you are trying to help. Mantids purposefully position themselves so that gravity assists with molting.
Fresh exoskeletons of mantids are very susceptible to tearing and quite soft. These exoskeletons are capable of stretching. However, the stretch will be permanent since the exoskeletons don’t have elasticity.
Mantids can survive a molt gone wrong, so long as they are able to consume food. However, there is a high likelihood of the next molt going wrong.
Dehydration
Generally, poor hydration, poor ventilation are the culprits behind molts gone wrong. In the case of the latter, mantids can easily suffocate and die.
Suffocation
Female mantids have a bad habit of consuming food until their bodies are enlarged. While this lowers their chances of dehydration, it also makes them more vulnerable to suffocation.
Parasites
Mantids are most vulnerable to the parasites known as horsehair worms and nematodes.
Be wary of ootheca that comes from the wild. It can also bring along wasp infestations. These wasps need to be located and then killed. If this is done sooner rather than later, it’s possible that mantid eggs will live.
Should you come across a parasitic infection, the only feasible step is to shield other mantids from infection.
Aging
Like all living beings, Mantids die of aging. Notable eye spotting is a clear sign of aging mantids. The same also applies when body parts turn dark and begin to drop off altogether.
What happens to Mantis before dying?
Right before death, mantids can puke brown-colored liquid and begin swiveling their heads repeatedly. Shortly after this, they will collapse and pass away.
Lethargy is another clear sign of impending death. Extensive time periods between feeding sessions are generally the causes of lethargy.
