Praying mantis can live for almost 8 to 12 months and lay eggs by mating with their partner. However, female praying mantises are known for brutal behavior toward their mates.
Do Praying Mantis Die After Laying Eggs? Praying mantis do not die after laying eggs, but they can die in winter due to deprivation of resources, slower metabolism, lesser energy to hunt, inability to enter diapause, and less tolerance to a lower temperature. You can detect the end of their lifespan by looking at their body color, which begins to turn brown from green.
A female praying mantis is stronger than its partner and survives aggressive strikes from their mate while fighting during mating.
However, these insects cannot resist extreme changes in the external environment and lose their lives when the conditions persist longer than they can tolerate.
Why do praying mantis die after laying eggs?
Female praying mantis can lay eggs many times in their life after mating with their male partners and get involved in deadly sexual encounters.
Male praying mantis can die during copulation, but the females usually survive after mating and keep laying for a long.
Moreover, they can survive in tropical weather but die in temperate zones after laying eggs as they have to deal with external stresses in winter.
Unavailability of food resources
They are predatory insects that prefer to eat other insects and tiny creatures, including reptiles and animals, as they cannot eat plant-based foods.
They commonly live on plant leaves and capture insects like aphids, mosquitoes, crickets, and other garden pests to meet their hunger.
However, there are lesser options for food for carnivorous insects as most of the crawling creatures are cold-blooded and hide in their underground tunnels or safe areas.
Most insects, like fruit flies and dragonflies, hibernate at low temperatures and become unavailable for praying mantis to attack. So, they have to remain hungry for a long and die sometimes.
It rarely happens that they can find living insects nearby to be used as food because these dead insect organisms can die due to deprivation of food resources.
Decreased metabolism and hunting efforts
The metabolic rate of insects drops in winter due to unfavorable weather because these cold-blooded insects hibernate at low temperatures.
They have less tolerance to cold temperatures and hide in safe places to avoid freezing to death. It is known as the diapause stage, when the growth rate of eggs gets slower.
In the same way, they usually become sluggish and feel lethargic due to slower metabolism and unavailability of nutrients and remain still most of the time.
Furthermore, they lose the efficiency to hunt their prey due to weaker body systems and ultimately die due to lack of food and lower body energy.
Low tolerance to temperature
Ideally, they need a temperature of 73 to 76 degrees Fahrenheit to perform well and suffer from decreased efficiency in capturing their prey in winter.
These insects lay eggs in the autumn or fall and cover them with froth. This covering becomes hard over time and protects them from cold weather.
However, these adult females cannot enter a diapause stage and are prone to death if they do not find a suitable warm place to live and take care of their eggs.
Furthermore, they remain active in the summer and fall when external temperature supports these cold-blooded creatures, but they usually die during hard frost.
They have a shorter lifespan of almost a year and die before the next spring season, but the risk of death is significant for those in colder climates.
When do praying mantis die after laying eggs?
Female praying mantis can lay a bulk of eggs every few days and even weeks, meaning they do not usually die after laying eggs.
Their survival depends on factors including the external temperature, humidity level, and health conditions, whether they are competent enough to tolerate minor or drastic changes.
Female praying mantis living in tropical regions can survive the changes as these places have warm weather and do not reach the maximum lower limit.
However, those native to temperate climates are more likely to die after laying eggs because they usually reproduce in the late summer or fall, followed by winter.
Freezing weather can stress their tiny bodies and probably lead to death when they find no food resources to meet their body requirements.
So, the climate plays a crucial role in their survival rate, and insects native to cold regions will die when the winter arrives without affecting their eggs protected by a hard covering.
Furthermore, they can survive after laying eggs and have a lesser risk of death in captivity because they have ideal conditions and plenty of food to eat.
How do you know praying mantis are dying after laying eggs?
You can estimate whether the praying mantis survives after laying eggs or are about to die by observing their physical condition and behavior.
Most commonly, these begin to refuse food when they do not feel comfortable in cold conditions and remain stuck to one place showing lesser movements.
It becomes difficult for these smaller insects to continue their activities due to lack of nutrition as they cannot quickly jump and attach their prey.
Accordingly, their perching power gets reduced when she does not attract male mates for mating and keeps lying under the surface of leaves.
So, decreased activity and refusal of food are the two primary symptoms for the end of her lifespan, in addition to changes in their body color.
Furthermore, the young and healthy praying mantis have green-colored bodies and begin to turn brown, slowly emerging from a few spots to a full-body color change.
These can take almost a few days to weeks to die when symptoms begin to appear due to external stresses on their body, which cannot enter a diapause stage.
How long do praying mantis survive after laying eggs?
The time female praying mantis takes to survive after laying eggs depends on the time of year, as they usually reproduce in the late summer or early fall.
Moreover, they can survive for a long time if they produce eggs from June to August because winter arrives in December, as they will have many months to go.
However, these egg-laying insects can live for a month or two if they produce eggs in the early fall, which starts in September and ends in November.
Accordingly, these insects can only survive until late falls are there as they cannot resist damage in the winter due to hard frost and significantly lower temperatures.
Furthermore, some healthy and bigger praying mantis, like the Chinese mantis, can avoid death for a long and dies in the mid of winter when they do not find food resources in their surroundings.
