Large Brown Mantis Facts

Archimantis latistyla is an insect native to Australia that is characterized by its impressive wingspan and mottled brown coloration.

This species has a strong voracious appetite for smaller prey and is shy but curious by nature, with a lifespan of several months.

Females of the species are the only ones able to reproduce, laying sticky egg cases called oothecae near the end of their life cycle.


The Large Brown Mantis originates from parts of Australia, Papua New Guinea, and New Caledonia.

They inhabit a variety of tropical and subtropical regions at sea level, as well as areas of higher elevation.

In their natural environment, they inhabit many diverse habitats.

These include temperate forests, where they reside on trunks and branches of vegetation in shady areas, along with wettish, temperate forests with an abundance of thick foliage.

They’ve even been observed in eucalyptus groves, and palm trees are another favored habitat.

Archimantis latistyla typically choose an area near the ground where they can position themselves to wait for prey.


Large Brown Mantes in the wild are typically predatory insects, relying on a diet made up of other insects and other small invertebrates.

Their diets typically consist primarily of spiders and crickets, though they will occasionally supplement them with small ants, moths, butterflies, cocoons, and caterpillars.

These insects must usually be smaller than the praying mantis itself, as they cannot consume larger prey that they cannot physically grab and handle.

In addition to consuming their prey for sustenance, Large Brown Mantes also consume supplementary substances in the form of pollen, sap, and plant juices.

In fact, these supplementary substances offer essential vitamins and minerals that may be missing from their chitinous diets.


Archimantis latistyla is typically quite shy and wary around humans and other animals.

This species is more likely to hide than confront when they feel threatened. When handled, Large Brown Mantises are usually calm and subdued.

They may attempt to crawl away, however, so it’s a good practice to be gentle and patient when handling them.

This species is also non-aggressive toward other animals, although they may see some of them as potential food sources, so it’s important to monitor interactions between any other animals and your mantis.

In general, the temperament of this species is quite mild and they make a great addition to any insect collection or even as a unique pet.


The Large Brown Mantis has a typical lifespan of between 6-12 months.

As with other species in the Mantodea order, they experience a complete metamorphosis, meaning they transition through many stages – egg, nymph, sub-adult, and adult.

The egg is laid across multiple separate oothecae (clusters of eggs) and can take up to three weeks to hatch.

Newly hatched nymphs look a lot like the adults but they can’t fly and are much smaller.

As they reach the sub-adult stage, they start to gain the ability to fly and can molt several times while they further develop into the adult stage. 

As adults, Archimantis latistyla will feed, mate and reproduce until the end of their life cycle.

To maximize their lifespan, it’s important to provide your mantis with a healthy, balanced diet and an environment ideal for their needs.


The Large Brown Mantis is a fascinating species when it comes to mating and reproduction.

Unlike most other mantis species, the Praying Mantis will mate in pairs, with the female leading the way.

It is best to introduce a potential mate into the female’s territory, where they will courtship, and then the female will capture the male.

It is essential that the male is not too large compared to the female, as this could result in the female devouring the mate. 

Once mating has finished, the female will go on to lay her eggs.

This species of mantis is capable of reaching full maturity in approximately 1-2 months and will become fully mature after multiple molts.

Where To Find Large Brown Mantis

If you’re interested in acquiring Archimantis latistyla, you may be able to find them in the wild or online from potential breeders or retailers.

The natural habitats of this species are rainforests and tropical regions.

Therefore, if you live in a tropical area, you may be able to find them in the wild.

However, it is typically safer and easier to acquire them from breeders or vendors.

In this case, you should conduct thorough research to find reputable breeders or vendors and purchase your mantis from a certified seller.

Furthermore, you should check for signs of health and any issues with the mantis you plan to purchase, such as missing limbs.

Additionally, if you have the ability to quarantine the mantis before introducing them into your habitat, it is recommended to do that to ensure the safety of the rest of your colony.

Large Brown Mantis Care

Caring for a Large Brown Mantis requires providing the right environment (temperature, humidity, lighting, and substrate) as well as a suitable diet of insects and supplemental vitamins.

You must also prepare to breed the mantis by understanding mating behavior and setting up a breeding tank.

Lastly, maintaining a healthy mantis requires health care considerations.

With the right information and guidance, you will be ready to enjoy the unique and fulfilling experience of keeping Archimantis latistyla.

Tank Requirements

The ideal tank for a Large Brown Mantis should be well-ventilated, with a secure lid.

A 5-10 gallon tank should be used for adult mantis, with smaller plastic cages or terrariums preferred for juvenile mantis.

The pH should be slightly acidic, around 6.0-7.5.

The hardness of the water should be kept soft, around 75-85 ppm, while the temperature should be kept at 75-85°F.

The terrarium substrate should be kept moist, such as peat moss or coconut fiber, and should be changed regularly.

Terrarium lighting should be provided by either fluorescent fixtures or overhead lighting, with 12 hours of light and 12 hours of darkness recommended to avoid stress and promote melanism in the mantis.

What Does Large Brown Mantis Eat?

Feeding Archimantis latistyla is essential for its health and growth.

Here are some tips for feeding your mantis: 

  • Offer a variety of food: Offer a variety of small insects such as crickets, grasshoppers, and small cockroaches. For supplementing their diet, you can offer small amounts of fruits and vegetables such as apples and squash.
  • Properly portion food: Offer food that’s appropriate for your mantis’s size. If they are not able to consume the food within a few hours, remove it from the enclosure.
  • Offer food daily: Feed your mantis 1-2 times per day.
  • Ensure fresh food: Provide fresh food for your mantis at each feeding. Discard any leftover food after 1-2 hours.
  • Don’t overfeed: Feed only as much food as your mantis can consume in a few minutes. If you offer too much food, it can cause health problems and attract pests.
  • Supervise feedings: For safety, always supervise feedings to make sure your mantis is not in danger from any of the food items.
