How Long Does A Mantis Live After Final Molt?

How Long Do Mantis Live After Final Molt? Mantises are known for their distinct appearance and their hunting techniques.

But, one question that many people have is how long do mantises live after their final molt?

After their final molt, mantises can live for around 28 days to up to several months. But, this depends on various factors such as species, environment, and food availability.

For example, in captivity, it’s not uncommon for mantises to live longer “after their final molt” than in the wild.

This is because they are provided with a more stable environment and food source.

However, if you want to learn more about the lifespans of mantises and what happens after their final molt then stick around!

The Final Molt Process

The average lifespan of a mantis, mainly depends on its size, for example, smaller mantises live for around 4–8 weeks whereas larger mantises can live up to 4-6 months.

During this time the mantis will go through 7 to 9 molts to reach adulthood. Once the mantis has reached adulthood, it will only have one final molt. After this final molt, the lifespan of the mantis will start to decrease.

However, the mantis will undergo a metamorphosis in its final molting process. This is where the mantis will change from its nymph form into an adult.

During this process, the mantis will grow wings and develop sexual maturity. Once the final molting stage is complete, the mantis will be fully grown and ready to mate.

After the final molt, mantises can live for around 28 days to up to several months depending on its size!

Does A Mantis Experience The Same Lifespan After Their Final Molt?

No, all mantis species do not experience the same lifespan after their final molt. The lifespan of a mantis after its final molt is mainly determined by the species of the mantis as well as its size!

For example, the Chinese mantid (Tenodera Sinensis) has an average lifespan of around 6-9 months in captivity. However, this can be much shorter in the wild due to predation and other environmental factors.

The European mantis (Mantis Religiosa) is another species of mantis with a different lifespan. The average lifespan of the European mantis is around 7–8 months for males and females 11–12 months.

There are just a couple of examples of how the lifespan of a mantis after its final molt can differ based on the species.

Other Factors That Influence Their Lifespan After Final Molt

A mantis molts, or sheds its exoskeleton, several times during its lifetime. The final molt, however, is different.

Once a mantis molts for the last time, it will only live for a few more months. So, what factors influence how long a mantis lives after its final molt?

Well, there are various factors that can influence how long a mantis lives after its final molt. These factors include the following:

  • Old Exoskeleton
  • The Environment
  • They Fall When Molt
  • The Food Availability
  • Disease, And Injury

Old Exoskeleton

One factor that can influence how long a mantis lives after its final molt is the old exoskeleton. The exoskeleton is what protects the mantis from predators and the environment.

As the mantis molts, its old exoskeleton will start to break down and become weaker. This makes the mantis more vulnerable to predators and other environmental factors.

The mantis will also be more susceptible to dehydration. In hot climates, the heat can cause the exoskeleton to become brittle, making it more likely to break.

In cold climates, the exoskeleton can provide some insulation, but the mantis will be more likely to die from exposure.

The Environment

Environmental factors, such as temperature and humidity, also play a significant role in how long a mantis lives after molting.

For example, if the temperature is too low, the mantis may not have enough time to properly harden its new exoskeleton before it dies of exposure.

Praying mantises like to live in warm and humid areas. In captivity, light water spray is used over the habitat to increase the humidity level inside the enclosure.

However, If the humidity is too high, on the other hand, the mantis may succumb to fungal infections. Dry conditions can cause the mantis to become weak and dehydrated which means it will have a harder time molting successfully.

They Fall When Molting

Another factor that can influence how long a mantis lives after molting is if they fall when molting. If the mantis falls during the molting process, it can cause the mantis to break its new exoskeleton.

This can be fatal for the mantis because the new exoskeleton is not fully hardened and is still vulnerable. Although this is extremely rare there have been cases where the mantis has fallen when molting.

With that said, if the mantis does fall, there is a chance that it will survive but this depends on the height it fell from and how well it lands.

Food Availability

Food availability is one of the major factors influencing how long a mantis lives after its final molt. If the mantis does not have enough food to eat, it will not have enough energy to molt properly.

This can lead to the mantis not being able to shed its old exoskeleton completely which can be fatal. If there’s an abundance of food, the mantis will be able to survive for a longer period of time.

If food is scarce, the mantis will eventually become weak and won’t be stronger enough to find a mate or protect itself, which can lead to its death.

Disease, And Injury

After a mantis molts for the final time, it only has a few months to live. This is because the molting process is very stressful on their bodies and weakens their immune system.

This is where they are more susceptible to disease and injury during this time. While mantises are tough insects, they are not immune to illness, and a number of diseases can shorten their lifespan.

Injuries are also common, particularly if the mantis is kept in captivity. Even a small cut can become infected, leading to serious health problems.

However, if they are well-nourished and have a strong immune system, they can live a full life after their final molt.

Can You Help A Mantis Live Longer After Its Final Molt?

Now, there’s no way to make a mantis live any longer after its final molt. However, there are a few things you can do to make sure they live a full and healthy life.

  • The first thing you can do is to make sure they are well-nourished. A healthy diet will help them to have a strong immune system and will give them the energy they need to molt properly.
  • You should also make sure their habitat is clean and free of any potential hazards. This includes removing anything that could fall on them or hurt them, such as sharp objects.
  • If you see a mantis that has molted, do not handle it or disturb it. Handling a molting mantis can cause it to break its new exoskeleton which can be fatal.
  • Finally, you should keep an eye on their health and look for any signs of illness or injury. If you see anything abnormal, take them to the vet right away.

By following these simple tips, you can help your mantis live a long and healthy life after its final molt!

How Do You Know When A Mantis Is Ready To Molt For The Last Time?

A mantis is ready to molt for the last time when it becomes sluggish and stops eating. The juvenile mantis, they will get what’s called “swollen wing buds” where their wings will eventually grow.

Mantises will also hang motionless upside down in their cage just before they molt. After molting for the final time, their wings will fully develop and they will be ready to mate.

Sign The Mantis Is Getting Ready To Molt:

  • Swollen wing buds
  • Sluggish and stops eating
  • Hang motionless upside down


So now you know how long do mantis live after their final molt? Mantises are amazing creatures that can live for several months after their final molt.

However, as mentioned in this article their lifespan is ultimately determined by a number of factors, including food availability, disease, and injury.

You can help your mantis live a long and healthy life by making sure they are well-nourished and its habitat is clean and free of hazards.

Keep an eye on their health and look for any signs of illness or injury. By following these simple tips, you can help your mantis enjoy a full life!
