How Long Can a Praying Mantis Live Without Its Head?

Praying mantis are smart creatures with incredible hunting skills for targeting their prey and attacking swiftly, but sometimes, they can be decapitated by their mates or predators.

How Long Can a Praying Mantis Live Without Its Head? A praying mantis can live without its head for almost 2 to 3 hours on average when the female mates decapitate the males during or after mating, or this body segment gets separated during a fight with prey or predators. They cannot survive for long because their sense of vision, touch, and eating get disturbed.

Only, a few people have seen these insects without a head because they cannot survive without a first body segment. These insects disappear or die as other insects usually eat them.

How long can a praying mantis survive without its head?

It is interesting to know that they can live without its head because it is not commonly seen in living organisms and rarely occurs in a few animals.

They cannot spend their whole life as decapitated entities because their role is crucial in living a healthy life, which means they can only manage to survive for some time.

In addition, the time duration for a praying mantis to live depends on the mating duration because these insects die after transferring sperm to the females.

Accordingly, it can last from a few minutes to several hours, depending on the time mating partners take to continue the copulation.

You can see them engaged in the copulation for as little as 15 to 20 minutes, but it can increase in a few cases and lasts from 5 to 6 hours.

Moreover, the extent of damage also determines their survival expectancy because the complete removal of the head can make them die earlier.

It is not wrong to consider that mating partners determine the chances of survival and lifespan of each other because they are known to decapitate one another for their survival.

How can a praying mantis lose its head?

Different reasons account for the problem when the praying mantis has to lose their head and die because it is not possible to live without a multifunctional body part.

One of the primary reasons is the aggressiveness of the female mating partners as she acts brutally and tries to kill the males for several reasons. She does not want an unfit male to claim paternity.

Moreover, it can be a defensive measure from her side to keep male praying mantis away from her when she is not interested in mating with him.

Starvation or hunger issues can also make them eat each other by getting control over their body after decapitation. Their efficiency in fighting gets reduced many times after losing it.

In addition, they can also get decapitated by predators when fighting for survival because the predatory insects or animals remove their heads before eating them.

Some brutal fights with prey animals can also cause damage to it because they have fragile bodies that can get a break with a forceful attack.

So, these praying mantis are adapted to survive without a head, but only for the short term because it is nearly impossible to live without eyes, antennae, and a mouth.

What happens if a praying mantis loses its head?

The survival rate of a praying mantis decreases quickly when it loses its head because it plays a crucial role in performing various functions.

Their triangular head contains essential organs that help them fight with prey and predators because they cannot see an incoming attacker without eyes.

They have five eyes, including two compound and three simple eyes located on their triangular heads that help them differentiate between light and dark.

They cannot see attackers without eyes, so they are more likely to die after attacks. Similarly, they cannot hunt prey effectively as they use mandibles to chew their bodies.

They have to lose their mandibles along with their head as their mouth is present there, which can also affect their eating behavior. They can’t eat, so they die of hunger.

Furthermore, two antennae are also present on the first segment of their body that are involved in chemical detection and aromas as they contain sensory receptors.

Their olfactory receptors are involved in courtship and feeding, as they touch objects to detect their chemical nature and suitability for consumption, in addition to pheromones detection.

What type of praying mantis can survive after losing its head?

Most commonly, the risk of losing its head is more for a male praying mantis than females because they are smaller and easily captured by her.

She can easily win the fight occurring between mating partners during copulation or after the mating process because these insects are involved in sexual cannibalism.

This sexual encounter proves deadly for the males commonly, but they can win over their mates rarely when they make a strategic attempt.

Moreover, male insects are less aggressive than females and wait for a chance to mate. They do know about the risk of death, but still, they have the courage to attempt.

In addition, babies or nymphs have a lesser risk of losing heads because they are not involved in sexual cannibalism due to the absence of wings.

They can only be attacked by predatory insects and smaller animals when their heads get separated from their bodies, resulting in decreased hunting capabilities as they cannot fight properly.

Can a praying mantis regrow their lost head back?

A praying mantis belongs to a category of arthropods and passes through several stages of molting when they remove old skin or hard covering on their abdomen.

This removal of an old exoskeleton is followed by the production of a newer covering that provides protection and support to their internal organs.

In addition, this molting process can help regrow lost limbs that can break or get devoured by predators during the fight.

However, they can regrow limbs to their original size, but it takes time as it gains a few millimeters in length with each successive molting stage.

In contrast, it is not possible for these insects to regrow their lost head back because the adult insects cannot pass through developmental stages again when the eggs develop into nymphs.

Metamorphosis allows eggs to become immature nymphs that look like adults significantly, as they have three segmented bodies but lack wings.

Accordingly, it is better not to expect praying mantis to get their heads back because molting cannot help them replace a lost body segment.
