The Japanese Boxer Mantis is a species of mantis found in Japan and East Asia.

The mantis naturally inhabits grasslands, woodlands, and meadows, and is adapted to living in cool, moist environments. 

This species is nocturnal and typically hides during the day, usually on the underside of leaves or in the crevices of rocks or logs.

They live a solitary lifestyle, so when in the wild, Acromantis japonica will mainly occupy small specific areas.


In the wild, the Japanese Boxer Mantis feeds on a variety of prey such as small insects, spiders, and even other mantids.

They have powerful crushing mandibles that make short work of their prey.

This diet is crucial for the health and well-being of these mantids, as they need the protein and other nutrients found in these prey items.

Adult mantids will seek to consume prey every 5-7 days, however, the feeding frequency may vary depending on the size of the mantis.


Japanese Boxer Mantis are typically shy and reclusive when it comes to being handled by humans and tend to hide or flee from contact.

They are also typically peaceful and non-aggressive toward other animals but can become defensive and territorial if provoked.

Although they are incredibly beautiful creatures, they should not be considered pets for regular handling – rather, it’s best to observe them from a distance.

If you wish to interact with Acromantis japonica, it is best to do so slowly and carefully to avoid stressing the animal.

As with other species of mantises, it is wise to wear protective gloves when handling these animals as their raptorial forelegs can cause injury.


Acromantis japonica has an average lifespan of up to 12 months, depending on its environment.

The lifecycle of the Japanese Boxer Mantis includes three stages: egg, nymph, and adult.

The egg stage is the development of the female mantis, where she will lay her eggs in an ootheca that contains several hundred eggs.

This ootheca is later protected by silk for protection from harsh weather conditions and predators.

The nymph stage is the development of the young mantids before they reach adulthood.

During this stage, the Japanese Mantis will molt several times over the course of several weeks or months before reaching its adult form.

The senescent stage is the last stage of the Japanese Boxer Mantis’ life, in which it will become increasingly weaker and its health will deteriorate.


The main steps of the mating process for Acromantis japonica are similar to those of other species of mantis.

A male will search for a female in his area and will make his presence known by vibrating the air with his wings.

If the female is interested, the two will engage in a ritual courtship dance as the male transfers his sperm into the female.

The mating process for this species can take anywhere from a few minutes to several hours, depending on how confident the female feels.

Once mating is complete, the female will lay her eggs on plants or twigs.

The average clutch size for the Japanese Boxer Mantis is approximately 150 eggs.

Once the eggs have hatched, the young nymphs will molt several times as they grow until they reach adulthood.

It is important to provide a good environment for your Boxer Mantis so that they can breed and be productive.

A good environment should include a stable temperature and humidity, with plenty of food to give them all the nourishment they need.

A well-fed and healthy mantis will be most likely to mate successfully and produce a healthy generation of offspring.
