One of the most distinctive features of mantids is their mouthparts, which have evolved to suit their carnivorous diet. However, not all mantid species have the same type of mouthparts or use them in the same way.

In this article, we will explore the world of mantid mouthparts, from classic scissor-like mandibles to more complex structures for precisely grasping prey.

Types of Mantid Mouthparts

Mantids have three types of mouthparts, each with a specific function:


The mandibles are the primary cutting and grinding jaws. They are strong and stout, used for holding and killing prey as well as breaking it down into smaller pieces.


The maxillae are located behind the mandibles and are responsible for pre-digesting the food before it enters the gut. They also help manipulate the food into a position for chewing by moving it around within the mouth.


The labium is a long tongue-like structure that extends from beneath the head of a mantid, used to suck fluids out of its prey after liquefaction has taken place in its digestive system.

Understanding these different mouthparts can give you insight into how these fascinating insects hunt and consume their prey, making them an interesting topic to study in entomology or biology courses.


The mandibles are the strong, toothed mouthparts located at the front of a mantid’s head.

Their primary function is cutting and grinding food. Mantids use their mandibles to catch and kill prey and break down tough parts of their meal, such as exoskeletons or bones.

Mandibles are adapted for different types of prey, with some species having shorter but stronger mandibles for crushing hard-bodied insects, while others have longer and more slender ones for catching fast-moving prey like flies. In addition to feeding, mantids also use their mandibles in self-defense when threatened by predators or humans.

Understanding the different types of mouthparts in mantids can help us appreciate how these insects have evolved specific adaptations to suit their hunting and feeding strategies. The next section will cover another important set of mouthparts – the maxillae – which play an essential role in pre-digesting food before it enters the gut.


The maxillae are the second pair of mouthparts in mantids and are located just behind the mandibles. They are usually long and slender, with sharp tips that curve inward to form a kind of scoop.

The primary function of the maxillae is pre-digestion. When hunting, mantids inject digestive enzymes into their prey using their saliva. The enzymes help break down the prey’s internal tissues so that they can be more easily consumed.

The maxillae also serve a manipulative function, helping the mantid to hold onto its prey while it feeds. In some species, these mouthparts have evolved into specialized structures called raptorial legs or “prey-grasping” forelegs, which are used for grasping and holding onto food items.

The maxillae play an important role in helping mantids obtain nutrients from their food sources by breaking down and manipulating their prey before digestion.


The labium is a long, tongue-like appendage extending from the mantid’s head. It is used for a variety of functions, including suction and liquefaction of prey.

When hunting, some species of mantids will use their labium to suck out the body fluids of their prey. This process begins with the mandibles cutting and grinding up the prey’s body into smaller pieces. The maxillae then pre-digest these pieces by secreting digestive enzymes onto them.

Finally, the labium is used to draw and consume the liquified remains.

In addition to its feeding function, some species of mantids also use their labium for defense. When threatened or attacked, they may raise their labium in a warning display to intimidate predators.

Overall, while the labium may seem like a simple structure at first glance, it plays an important role in both feeding and defense for many species of mantids.

Functions of Mouthparts

Mantids, like most insects, have different types of mouthparts that are specialized for different functions. The three primary types of mantid mouthparts are mandibles, maxillae, and labium.

The mandibles are used for cutting and grinding food. They are strong and sharp and can easily break down prey into small pieces that can be swallowed whole. The maxillae are used for pre-digestion and manipulation of food.

They have tiny hooks that help to hold onto prey while the enzymes in the mantid’s saliva begin to break it down.

The labium is a long appendage hanging down from the head’s front. It is used for the suction and liquefaction of food. Once the enzymes in the saliva have begun to break down the prey’s tissues, the labium is inserted into its body cavity, where it sucks out its liquefied contents.

These three types of mouthparts work together to allow mantids to capture and consume their prey efficiently. By using their strong mandibles to cut through tough exoskeletons, their maxillae to begin breaking down soft tissues, and their labium to suck out all remaining fluids – they make quick work of even large insects or other arthropods!

In conclusion, understanding how each type of mouthpart works together gives us a better insight into how these fascinating creatures hunt and feed on their prey!

Mandibles: Cutting and Grinding

The mandibles of a mantid are the most noticeable and prominent part of their mouthparts. They are used for cutting and grinding up prey into smaller pieces that can be easily consumed. The mandibles are on either side of the mantid’s head and are designed to move horizontally, much like scissors.

Mantids have strong jaw muscles that allow them to clamp down on their prey with great force. Their mandibles are also extremely sharp, making it easier to tear through tough exoskeletons or shells.

In addition to cutting and grinding, the mandibles also play a role in manipulating food within the mantid’s mouth. Once food has been cut up into smaller pieces, it is moved around by the mandibles until it reaches the maxillae and labium, where further digestion takes place.

Overall, the mandibles of a mantid serve an important function in helping these insects catch and consume their prey effectively.

Maxillae: Pre-digestion and Manipulation

The maxillae are the mouthparts responsible for pre-digesting and manipulating food before it reaches the digestive system. These appendages are located behind the mandibles and serve a wide range of functions.

In some species of mantids, the maxillae secrete enzymes that break down proteins and carbohydrates in prey items. This process is known as extraoral digestion, which means that digestion begins outside of the body. The liquefied food is then sucked up through a small channel in the labium.

Other species use their maxillae to manipulate food items into position so they can be consumed more easily. Some mantids will grip onto their prey with their mandibles while using their maxillae to pull away any unwanted parts, such as wings or legs.

Overall, the maxillae play an essential role in ensuring that mantids can efficiently consume their prey. By pre-digesting and manipulating food before it reaches the digestive tract, these mouthparts allow for quicker nutrient absorption and help prevent indigestion or blockages within the gut.

Labium: Suction and Liquefaction

The labium is the final segment of the mantid’s head and is also known as the lower lip. It is a flexible, muscular structure that has evolved to become an incredibly efficient feeding tool.

When a mantid captures its prey with its mandibles and maxillae, it uses its labium to complete the feeding process. The labium is adapted for suction and liquefaction, allowing it to extract nutrients from even the smallest prey items.

To feed, the mantid presses its labium against its prey and begins to secrete digestive enzymes into its mouth. These enzymes break down the soft tissues of the insect, transforming them into a nutrient-rich liquid that can be easily consumed by the mantid.

As this liquid accumulates in the space between the labium plates, tiny muscles inside each plate contract rapidly, creating sucking pressure that draws up more liquid from inside the insect’s body cavity. This process continues until all of the available nutrients have been extracted.

In conclusion, while all three types of mantis mouthparts work together like finely tuned instruments during feeding time, it’s clear that each part has evolved for a particular purpose. By understanding these different roles, we can gain deeper insight into how these fascinating insects have survived and thrived for millions of years.

FAQs on the different types of mantid mouthparts and their functions
