Praying mantises are not social insects as they can harm other insects and animals due to their cannibalistic nature, which leads to eating other organisms for nutrition.
Do Praying Mantises Eat Their Babies? Praying mantises can eat their babies and siblings when they have no food to eat because they produce a large number of eggs at one time, and they eat a few eggs for nutrition. Nymphs can also eat other siblings to get food, so it is better to keep two insects separate when they enter a second molting stage.
It is not challenging to keep praying mantises as pets as they need care and cannot be mixed with other pet insects and animals.
Moreover, sexual cannibalism is common in these insects as they eat their mating partners during or after copulation.
Why do praying mantises eat their babies?
These insects are cannibalistic organisms that prefer to eat the organisms from the same species for nutrition. It is common among a few animals and insects as they devour their babies.
A female praying mantis can lay hundreds of eggs at once, giving rise to a few dozen or almost 350 to 400 new eggs in a day. Moreover, they can manage to eat a few of these new eggs.
This behavior of cannibalism helps insects to control overgrowing populations when they do not have enough resources to feed their young ones and ensure their healthy growth.
Accordingly, the members of the same species or the adult parents begin to eat their eggs to stop them from becoming adults and obtain nutrition from them.
In addition, injured or immature eggs or young ones are more prone to attacks by adults as they cannot develop into mature organisms and seems to be a burden as they only eat food.
It can be a way to adjust the caste ratios and maintain a balance between different genders.
Furthermore, it can be a ritual or survival cannibalism that helps them avoid death due to lack of food because they begin killing their babies when they find no food to eat.
So, they usually eat newly produced eggs passing through developmental stages to provide healthy nutrients to body cells for converting them into energy.
What happens when praying mantises eat their babies?
They produce a lot of eggs at one time as these hundreds of eggs need nourishment to develop properly and turn into adults after proper care by the adults.
However, some factors can put pressure on mature adults when they cannot feed newly produced organisms passing through molting stages, like a shortage of food.
These female insects commonly lay eggs on the plants like stem regions, which can give rise to more than 100 young offspring, as each eggshell contains around 150 to 200 young mantises.
These eggs are usually protected within a papery covering or a frothy mass known as ootheca released by abdominal glands. It becomes hard over time and turns into a protective coat.
This covering helps avoid damage in winter and ensures protection from damage as a hard shell covers these eggs.
Moreover, these eggs do not get enough time and care to become adults and will die as miniature replicas of their parents.
So, the female knows how to deal with situations and kills babies to reduce competition for food and allows only a few eggs to become adults by providing nourishment.
Do praying mantises babies eat each other?
Cannibalistic behavior is common in adults and growing praying mantises, as they can attack each other to ensure survival.
In the same way, they can also eat their siblings and babies when they have no other option to meet their body requirements and devour the eggs or babies going through molting stages.
It seems like a pathetic situation for newborn babies when they do not get a chance to live and are killed by their parents and adult siblings.
It usually occurs due to survival cannibalism when the adults have no other options to consider by leaving the young ones and risking their lives.
Accordingly, they benefit from the egg-laying capabilities of the female as she can easily make up the loss by producing hundreds of new eggs at once.
In addition, they do not take more than a few minutes to break an eggshell and devour the young ones with their raptorial forelegs having spines on them.
Eggs, nymphs, and adults are three stages in the lifecycle of these insects, and their parents or siblings can kill them for nutrition at any stage.
The nymphs are wingless adults who need food on alternate days until they become mature adults with wings. These nymphs can also attack each other when they are not getting enough food.
So, the eggs, nymphs, or even adults are not safe from attacks by their parents and siblings, as they are mature adults and need food to survive and keep their population at an ideal number.
Can baby praying mantises live together?
A large number of praying mantises emerge from eggs when they hatch properly in the springtime. It leads to competition among them to access food and water sources.
It is not safe to keep most of the baby praying mantises together when they become nymphs as their cannibalistic nature develops at the stage after becoming wingless adults.
You can keep them in one place when they are at the first molting stage, but separating them at the second and third molting stages becomes essential when they become deadly for each other.
Moreover, a large cage with hiding spots can provide an ideal environment as they can run away to ensure safety when siblings attack each other.
The risk of attacks can be reduced by providing excess food as they think to cannibalize their babies and siblings when they have no food to meet their body requirements.
Giving them a separate house or tank is better when they become nymphs because they prefer to remain alone and are not social insects.
Some of their communal species can live together without harming each other as they are compatible. You can choose docile species to keep them in one cage.
The presence of larger or mature adults and smaller nymphs or immature adults in the same tank can pose a problem for the smaller ones. It is not safe to keep them together in one place.
Most of their species are cannibalistic by nature and attack organisms of the same species and destroy their bodies in only a few minutes.
