  2. The compound eyes have thousands of individual lenses called ommatidia, allowing mantids to create a 3D image of their surroundings and detect movement from up to 20 meters away.
  3. Mantids can see a broad spectrum of colors, including ultraviolet light, which helps them distinguish between prey items and locate flowers with UV markings.
  4. Mantids’ vision is specialized for hunting, with the ability to detect movement, perceive long distances, and track fast-moving targets.
  5. Ultraviolet vision in mantids may play a role in mate selection and adds an extra dimension to their visual capabilities.

What Are Mantid Eyes?

Mantids, also known as praying mantises, have some of the animal kingdom’s most unique and fascinating eyes. These insects are known for their ability to strike prey accurately with their sharp forelimbs, and their vision plays a crucial role in this process.

The Structure Of Mantid Eyes: Mantids have two large compound eyes on either side of their head, which contain thousands of individual lenses called ommatidia. In addition to these compound eyes, they also have three simple eyes called ocelli situated between them.

Compound Eyes: The compound eyes provide mantids with excellent spatial awareness and depth perception. This is because each ommatidium captures light from a slightly different angle, allowing the insect’s brain to create a 3D image of its surroundings.

Three Ocelli: The three ocelli are located on top of the head and function independently from the compound eyes. They are responsible for detecting changes in light intensity and can help mantids navigate during low-light conditions such as dusk or dawn.

How Mantid Eyes Function: Mantid vision is highly specialized for hunting prey. They possess several visual adaptations that allow them to detect movement over long distances and track fast-moving targets:

Movement Detection: Their large compound eyes can detect even small movements from up to 20 meters away!

Color Detection: Mantids can see colors ranging from ultraviolet (UV) to green-yellow hues which helps them distinguish between potential prey items.

Long Distance Vision: Although they do not have telescopic vision like eagles or hawks, mantids’ multifaceted bug-eyes still provide some degree of long-distance focus when tracking moving objects across open spaces.

Ultra Violet Vision: Many flowers reflect UV light more strongly than visible light – making it easier for pollinators like bees or butterflies (and yes even – Praying Mantises) to find them.

In conclusion, mantids have a complex and fascinating visual system that allows them to detect prey quickly and accurately. Their compound eyes and simple ocelli work together to provide spatial awareness, depth perception, color detection, long-distance focus, and even ultraviolet vision – all of which make them one of the most effective predators in the insect world.

The Structure Of Mantid Eyes

Mantids, like many other insects, have compound eyes made up of numerous tiny lenses. These lenses work together to form an image that the mantid can see.

Interestingly, each lens in a mantid’s eye points in a slightly different direction, which allows for an extremely wide field of view.

In addition to compound eyes, mantids also have three simple eyes called ocelli. These are located on the top of their heads and are used primarily for detecting changes in light intensity.

While these simple eyes do not provide as much visual information as the compound eyes do, they are still an important part of the mantid’s vision system.

Overall, the combination of both compound and simple eyes gives mantids a unique perspective on their surroundings. Their ability to perceive movement and distinguish colors makes them formidable predators in their environment.

Compound Eyes

Mantids have compound eyes, which consist of thousands of individual lenses called ommatidia. Each ommatidium is responsible for capturing a small portion of the visual field, and all of them work together to create a complete image.

Interestingly, each ommatidium has its own photoreceptor cells that can detect light intensity and color. This allows mantids to see a broad spectrum of colors, including ultraviolet light (which humans cannot see). Additionally, their compound eyes allow for excellent peripheral vision, giving them an almost 360-degree view of their surroundings.

The size and number of ommatidia in mantids’ eyes can vary depending on the species. For example, some species have larger eyes with more ommatidia than others. This variation may be due to differences in hunting strategies or environmental factors.

Overall, the structure and function of mantid compound eyes allow these insects to be highly effective hunters, able to detect movement from prey as well as identify potential threats in their environment.

Three Ocelli

In addition to their compound eyes, mantids also have three ocelli, simple eyes on the top of their heads. The ocelli are much smaller than the compound eyes and do not provide the same level of visual information.

The primary function of the ocelli is to detect changes in light intensity. This allows mantids to detect movement even when it’s too dark for their compound eyes to see clearly. The ocelli are especially sensitive to sudden changes in light, such as those caused by a predator approaching.

Interestingly, recent research has suggested that some species of mantids may also use their ocelli for other purposes. For example, researchers have found evidence that certain species can use their ocelli to detect polarized light, which could help them navigate and find prey more effectively.

Overall, while the ocelli may not be as sophisticated as the compound eyes, they play an important role in helping mantids survive and thrive in their environment.

How Mantid Eyes Function

Mantids have incredibly complex eyes, with different parts serving different purposes. One of the most impressive aspects of mantid vision is its ability to detect movement quickly and accurately.

Mantids use two large compound eyes, which are made up of thousands of individual lenses called ommatidia. These lenses each capture a small part of the visual field and combine to form a detailed image in the brain.

This enables mantids to see objects in front of them clearly, even when they are moving quickly.

In addition to their compound eyes, mantids have three simple eyes called ocelli on the top of their head. These are used primarily for detecting changes in light levels and help orientate themselves in space.

One fascinating aspect of mantid vision is their ability to perceive ultraviolet light. This allows them to detect patterns on flowers that are invisible to humans, which can be useful for locating prey or identifying potential mates.

Overall, mantid vision is incredibly sophisticated and crucial to their survival as ambush predators. By understanding how these remarkable creatures see the world around them, we can better appreciate the complexity and beauty of nature’s designs.

Movement Detection

Mantids have a remarkable ability to detect even the slightest movement in their surroundings. This is due to the fact that their compound eyes are made up of thousands of ommatidia, which can pick up on slight changes in light and shadow.

Each ommatidium acts like an individual eye, and when all of them work together, they create a highly sensitive visual system.

In addition to their compound eyes, mantids also have three simple eyes called ocelli. These eyes are located on top of the head and are mainly used for detecting changes in light intensity. While they cannot form detailed images like compound eyes, they help mantids navigate their environment.

Overall, the combination of both types of eyes allows mantids to be incredibly effective predators. They can detect faraway prey using their long-distance vision or sensing movement with their compound eyes.

Once they’ve locked onto a target, they use their ultra-violet vision to track it down before pouncing with lightning-fast reflexes.

It’s clear that mantids have evolved highly specialized visual systems that allow them to thrive in diverse environments around the world. Whether you’re fascinated by these insects or just appreciate nature’s ingenuity, there’s no denying that mantid eyes are truly incredible feats of evolution!

Color Detection

Mantids are able to detect colors, although their color vision may not be as detailed as humans. They have several types of photoreceptors in their eyes that allow them to see different wavelengths of light.

Their compound eyes contain many ommatidia, which are individual units with their own photoreceptor cells.

One interesting fact is that mantids can see ultraviolet light outside the visible spectrum for humans. This allows them to detect patterns on flowers and other objects that are invisible to us.

However, it’s important to note that color vision in mantids may not be as important for hunting as movement detection and long-distance vision. Coloration in prey is often used as a form of camouflage, and mantids rely more heavily on detecting movement than on coloration when hunting.

In conclusion, while mantids can detect colors, they may not play as significant a role in their behavior as other visual cues like movement detection and long-distance vision.

Long Distance Vision

Mantids have excellent eyesight and are able to see objects from a distance. Their compound eyes are made up of many individual lenses, allowing them to perceive their surroundings in great detail. They also have three ocelli, which are simple eyes that detect light intensity and movement.

Mantids use their long-distance vision for hunting and navigating through their environment. They are able to spot prey from a considerable distance and approach it stealthily until they are close enough to strike. In addition, they use their vision to navigate through complex environments such as forests or grasslands.

Mantids can see ultraviolet light, which is invisible to the human eye. This ability helps them locate flowers that have nectar guides visible only in ultraviolet light. They also use this vision to determine the age and sex of other mantids during mating rituals.

In summary, mantids have exceptional long-distance vision thanks to their compound eyes and ocelli. Their ability to see in ultraviolet light gives them an advantage in finding food and mates in their environment.

Ultra Violet Vision

Mantids have the ability to see ultraviolet light, which is not visible to the human eye. This gives them an advantage when it comes to hunting prey, as many insects and flowers have ultraviolet markings that can aid in their detection.

The exact mechanism by which mantids are able to see UV light is not yet fully understood. However, studies suggest that they have specialized cells in their eyes called ommatidia that are more sensitive to UV wavelengths than other wavelengths of light.

In addition to helping with hunting and navigation, some research suggests that ultraviolet vision may also play a role in mate selection for certain species of mantids. Females of some species seem to be attracted to males with brighter UV markings on their bodies.

Overall, the ability of mantids to see ultraviolet light adds an interesting dimension to their visual capabilities and helps them thrive in their natural environments.


Mantids are fascinating insects that have evolved unique eyes to suit their predatory lifestyle. Their compound eyes provide excellent motion detection and color vision, while their three ocelli allow for long-distance vision and UV sensitivity.

These specialized eyes help mantids detect prey and avoid danger from predators. Understanding the structure and function of mantid eyes can provide valuable insights into insect vision as a whole and possibly inspire new technologies in the future.

So next time you encounter a praying mantis, take a moment to appreciate its remarkable visual system.
