How do Praying Mantis Communicate With Each Other?

Praying mantis are lone fighters. They do not live in colonies or families, which makes sense, taking their cannibalistic features into account. It’s probably not the best start to a family get-together to admit that you ate all your siblings. Since praying mantis are always found alone, or in some cases during their mating process, you might be wondering if praying mantis have a way to communicate at all.

As a whole, praying mantis communicate via pheromones. They only communicate with each other during mating season. Females attract males for mating by releasing pheromones. Praying mantis have eyes and one ear, but these are not used for communication but only for hunting and for detecting threats in the wild.

Do Praying Mantis Communicate?

Praying mantis are solitary insects, meaning that they do not live together with other mantises. Even in captivity, it is best to keep each praying mantis in an individual tank. Otherwise, chances are high that they kill each other. 

There are very few exceptions to that rule. One of the exceptions is the Ghost Mantis. Several Ghost Mantis can be kept together throughout their lives and they will not show aggression towards each other as long as they receive enough food.

But in general, praying mantis live alone, in nature as well as in captivity. Therefore the only reason to communicate with each other is their urge to reproduce.

Praying Mantis Communicate Via Pheromones

When a female praying mantis is ready to mate, she releases pheromones to attract any male praying mantis of her species. The male can sense the pheromones in a radius of up to 110 yards. This comes in very handy as most female praying mantis cannot fly and need the males to come to them in order to mate.

Sending out pheromones only means that the female is theoretically willing to mate, but it does not mean, that the male is safe to approach her. He might still be used as a snack instead of mating.

Praying Mantis Communicate Through Sounds

Some praying mantis species are known for making sounds. Praying mantis have two sets of wings. The outer set, which is used for camouflage or to scare predators away and to protect the inner set, which is very fragile and made for flying (at least for the male).

The mantis can make a sound by rubbing these inner wings set against the abdomen. This sound is meant to display threats.

Sometimes when a praying mantis sees another praying mantis it can use these sounds to warn the other mantis to stay away.

How do Praying Mantis Interact With Each Other?

Most praying mantis do not interact with other praying mantis until they reach adulthood and are ready to mate. Approaching a praying mantis can be a life-threatening matter for any potential prey. That also includes other praying mantis. Therefore it is not surprising, that they don’t like each other’s company too much.

As a whole, the only two occasions in which praying mantis might interact with each other after hatching are either mating or killing and eating each other. The rest of the time praying mantis will try to avoid each other.

Not every praying mantis species shows these aggressions towards each other, but most do.

Can Praying Mantis Hear?

The majority of praying mantis species have an ear, but it’s nothing like human ears.

The single ear of the praying mantis is located on the bottom of their thorax, in the middle of their “chest”. This ear is sensitive to ultrasonic hearing. That means that praying mantis are able to hear a very high frequency above 20,000 hertz. This is just outside the range of human hearing. 

This ultrasonic ear allows praying mantis to hear bats flying. Since many male praying mantises choose to fly at night to search for a female to mate with, bats are among the very few predators they have to face.

When a praying mantis senses an approaching bat, it starts dropping from the sky by spiraling downwards to avoid being caught by the bat.

As a whole, praying mantis can hear, but their hearing is very specific and only includes frequencies above 20,000 hertz that allows them to stay away from the predators of the night: The bats.

Can Praying Mantis Smell?

Praying mantis are able to smell. When a female praying mantis is willing to mate, she sends out pheromones for the male. The male smells these pheromones and follows them to find the female. The sense of smell of praying mantis is limited to sensing the pheromones from each other. 

Can Praying Mantis See?

When you see a praying mantis, it is hard to not look into these crazy huge, compound eyes. These eyes allow the praying mantis to see three-dimensional. This does not seem too impressive from a human point of view, but in fact, praying mantis are the only insects in the world, that we know of, that can see in 3D. No other insect can see three dimensions.

As a whole, praying mantis can see fairly well. Their main sense is seeing, which they primarily use for hunting their prey. The three-dimensional view is based on movements. This is why a praying mantis will wait until prey approaches and attacks quickly.

Praying mantis only eats living creatures. That makes sense, given the fact, that their seeing is based on movements around them. They will not take a dead and therefore not moving insect as prey.

The eyes of the praying mantis are made of thousands of light receptors. These are called ommatidia. If you look into the eyes of a praying mantis, you seem to see a pupil.

This dark spot is actually not a pupil but many light receptors that absorb all wavelengths of light and therefore appear black. It only looks like a pupil because of the angle.

All the light receptors around that dark pupil-like spot reflect only certain wavelengths.

This is why the rest of the eye can appear in crazy colors such as of course white, but also green, brown, and even purple.
