Yes, praying mantis do lay eggs but their eggs do not resemble any bird’s or reptile’s eggs. The female mantis typically lays foamy case made up of frothy liquid encasing 100 to 200 eggs. The foamy case protects the eggs from wind and rain. Many other insects guard their eggs in pretty much the same way. For instance, moths are known to protect their eggs with their stingy hairs. Let us now study when do praying mantis eggs lay eggs and when do these eggs hatch.
When Do Praying Mantis Lay Eggs?
Just like praying mantis can mate any time during the year the female mantis lays eggs without any particular season. Nonetheless, the female mantis typically deposits eggs in spring.
When Do Praying Mantis Eggs Hatch?
Well, it generally depends on the species. The eggs of the smaller mantis take 21 to 28 days to hatch while the bigger species takes 28 to 42 days to hatch eggs. Similarly, the smaller female likely deposits 100 eggs in a single ootheca whereas the bigger female can lay as many as 200 eggs in a sack.
All eggs in the same ootheca hatch at the same time. The mantis eggs hatch in summer because the pest insects emerge in summer. The newly hatched baby praying mantis need tiny insects to feed on. Therefore, even in summer the hatching needs a couple of weeks of warm weather.
The female mantis is clever enough to deposit eggs atop one-foot tall grass but sometimes it lays eggs on twigs. The higher is the egg from the ground, the safer it is.
What happens when the Eggs Hatch?
Soon after hatching, the baby mantis will crawl within the protective case and hangs on silken threads 2 inches below the case. Moments later, the young mantis will land on the ground and find its own way of surviving in the wild. It all happens with 60 to 120 minutes.
The ootheca doesn’t change its texture even when the hatching is about to occur. Therefore, it’s pretty hard to assess if the mantis eggs are actually hatched unless a baby mantis crawls out of the case.
Yes they probably do, particularly if the female produces eggs right before the frost. This behavior isn’t only observed in mantids in fact the death of a female soon after laying eggs is pretty common in the insect world. No wonder, praying mantis are pretty infamous for exhibiting some of the most bizarre behavioral adaptations. For instance, the female (though only occasionally) eats the male during mating.
Similarly the female mantis doesn’t only cannibalize her mating partner it also dies soon after laying eggs. However, this particularly behavior isn’t only limited to the praying mantis. Many bugs such as honey bees also die after producing eggs. Honey bee dies because its genitals explode. Perhaps this is a necessary part of an insect’s life cycle. Small mantis species live around 2 to 3 months and it’s reasonable to assume that their shorter life span might be due to this behavior.
The egg-laying process begins in the adult female and ends with the first frost. The sac measures 1 inch (3cm) in diameter. The sac is about 1 inch (3 cm) in length, rectangular with rounded corners and tan-to-white. How are praying mantis egg capsules made? When do the egg sacs hatch and what do they look like? Find out how to care and maintain these fascinating insects eggs.
Information about Praying Mantis Egg Sac, Case, Ootheca
Praying mantis in your garden provides a safe and biological way to fight the summer’s flurry of insects. They are omnivorous and will eat any kind of food. However, they provide a natural pest control solution for mosquitoes, crickets moths, flies, and moths.
They go through a complicated life cycle that includes cannibalistic breeding, overwintering eggs and adulthood. You can find prayer mantis egg sacs across North America. However, in colder regions you may need to purchase them for your garden.
Start by looking up information about the praying mantis egg Sacs. When do mantis sacs hatch? When spring temperatures warm up, these predatory bugs begin to emerge out of their casings. This means that you should begin looking for cases in the late fall or early spring.
Females lay their eggs on stems, twigs, and walls. While the sacs may be difficult to spot, they will become more evident when trees lose their leaves. How many praying mantises lay eggs? Even though it is a small insect, the praying mantis can lay up to 300 eggs per sac. About one-fifth (or less) of these nymphs will live to adulthood. Therefore, it is vital to protect egg sacs in order to protect future generations of predators.
What does a Praying Mantis Egg Sac look like?
The eggs come surrounded by a foamy substance that hardens into their casing. The foam is called ootheca. If you are lucky enough to find one, you can observe the sac hatch in a glass or plastic container that has air holes. If the insect is immature, they will hatch within four to six week if brought indoors. However, they can be hatched immediately if found late in winter. The nymphs are miniature adults who will have voracious appetites and look just like adults. Let them go outside to get started in their work. The babies will die if you encourage hatching and release when the temperatures outside are below freezing.
How to Encourage Praying Mantis Gardening?
To encourage praying mantis, it is a simple thing to stop pesticide use. These insects are vulnerable to many kinds of chemical preparations. Prayer mantises are very susceptible to chemical preparations. If they don’t appear, then the population might have died. Egg sacs can be purchased and used to hatch new groups of insects in your garden. If you want to care for newly hatched baby nymphs, separate them into individual vials. They will either eat each other or be separated.
In each container, place a moist cottonball and give them fruit flies or other aphids. The task of keeping mantis babies in check until spring can be tedious so order your casings in the winter. Hatch them for spring release. You can also refrigerate eggs casings for a month in order to prevent hatching. Then, warm the sac slowly for a warm-season release.
Can you have Praying Mantis Eggs in your Garden?
You may have seen, or even beenfriended by praying mantises within your garden in this growing season. Although most adult mantises die in late fall and early Winter, there are likely some garden ornaments that they left behind.
All alien-looking mantises possess a pair feisty grasping legs which allow them catch their prey. They also have long, straight legs that allow them stomp and a triangular, twisting head that allows them to see around them. Praying mantise is the only insect capable of looking over its shoulder. They are able to wait motionless, and then use camouflage in order to capture unsuspecting insects. Some tropical species mimic orchid flowers, leaves and twigs. They can alter their color over time to match their surroundings.
The Chinese mantis and the Carolina one are the most common in Central Illinois. The Chinese mantis grows up to five feet longer than the Carolina one. They are typically tan to light brown, with some green and yellow stripes. Carolina mantises grow up to 2 1/2″ in length and can come in a variety colors (green, brown, and gray).
The Chinese mantis adult female will lay her egg case (known as an ootheca) on twigs. She only requires that the area holds her body weight, and is slightly vertical. This makes brick siding perfect.
After laying the egg, the ootheca rapidly hardens to allow for a winter sleep. Mothers will eventually die shortly after. These egg cases, which you will find in fall or winter, are light brown and approximately 1.5 inches in width. They look almost like foam insulation. Each foamy insulation case houses hundreds of mantis egg shells that are strong enough to withstand winter’s storms.
Carolina praying mantis teethecas are smaller and flatter than trilobites, and they are more common on flat vertical surfaces.
If the eggs must be removed from a wall they can be transferred to a shelter. Don’t leave an egg container on the ground. The eggs will be eaten by ants quickly.
Next spring will see the Nymphs emerge like an erupting from foam appendages. Then they will begin their journey to discover insects. This may include their brothers or sisters. The majority (or all) of the mantises born from an egg case will die due to starvation or cannibalism. They are territorial so by the end the summer there is usually only one remaining adult.
Is it possible for the Praying Mantis Sac to be relocated?
You can move the egg case to another location in your garden. Cut the stem with the eggcase attached, then move to another stem or crotch in an shrub about a foot off the ground. This will provide cover for the 100-200 tiny mantises hatching from the sac. To make sure the stem/case remains in place, you might use twine or wire to attach it. You should not place the egg sacs on the ground, as they will be eaten by ants.
Amazingly, there is over 2,400 different species of mantises worldwide. These are both in temperate and tropical environments. By blending into their surroundings, Mantises can camouflage themselves. Mantises have excellent vision and are good at eating insects. Although they don’t eat only certain insects, I love to have them in my yard!

How Long does it take for the Praying Mantis Eggs to Hatch?
Hatching needs at least 10-15 days of continuous warm temperatures (75-80degF, >50% RH ) to occur. This can take up to 6 week to complete. Once hatching is completed, the young mantids begin to look for food. The hatching process takes only a few hours once the egg sack has begun. For continued activity, Mantids will prefer temperatures over 60F.
How Many Praying Mantids Can You Find in One Egg Case?
Each egg case containing 50-200 eggs of the praying mantis is called an “ootheca” and it is collected from nature.
How Many Egg Cases Do I Need?
We recommend using three cases per 5,000 sq. 10 to 100 cases per acre. You need to space out every egg case in order to reduce the chance of mantid cannibalism.
How to Look After praying mantis eggs in your garden?
Did you ever find a brown, polystyrene mass on a shrub or tree in your garden? Many people find these odd-looking forms on their garden plants in autumn when the leaves start to turn brown. Many people believe it to be a cocoon. Although it is a sign insect activity, this is not a cocoon. This foamy structure can be identified as the egg case of a praying Mantis (an invertebrate family Manidae).
A praying mantis female deposits many eggs shortly after her mating. The eggs she lays may only be a handful or hundreds. The mother mantis covers her eggs with a thick substance that hardens rapidly to a consistency comparable to polystyrene. This egg case, also known as an “ootheca”, is also called a ootheca. After mating once, several oothecae may be produced by a single female mantis.
Praying mantises often lay their eggs in autumn or late summer. The young then develop within the ootheca throughout the winter. The egg case’s foamy structure protects offspring from cold and predators. Tiny mantis-nymphs hatch while their eggs are still in the eggcase.
Depending on their species and environmental factors, it may take between three and six months for the nymphs to emerge from the mouth of the ootheca. The young praying mantises are ready to hunt other small insects and will emerge from the protective foam cover in the spring or early the summer. They start to disperse immediately in search of food.
You might be tempted bring your ootheca inside if it is in fall or winter. Warning! The warmth of your house will feel like spring to the baby ants waiting to emerge. You don’t want to have 400 praying mantises crawling up your walls.
If you have collected an ootheca for the purpose of watching it hatch in the spring, place it in your refrigerator. For spring, you can keep the ootheca inside a terrarium. You shouldn’t keep young mantises in their cages. They are in hunting mode and will eat all of their siblings. Let them roam around your garden and help you with pest control.
It is possible to identify the particular species of mantid by its egg cases. Bugguide.net allows you to identify the egg case that you find. This online community of naturalists shares photos of spiders, insects, and other related creatures. These are photos of some of the most common mantids found in North America.
The egg case at the top of this article is a Chinese-mantis (Tenodera sensis sinensis). This species is a native of China, Asia and North America. Chinese mantis eggs can be purchased from commercial biocontrol suppliers for gardeners and nurseries looking to use the mantis species to control pests.

The male mounts on the bigger female from her back.
While male and female praying mantis share certain characteristics they do have few dissimilarities too. The difference between male and female mantis isn’t so obvious when they are young; it becomes more pronounced with age. You’re more likely to recognize praying mantis male or female when they have reached adulthood. Let’s have a look at each of them and see if they are sexually dimorphic.
Difference Between Male and Female Praying Mantis – Male and Female Praying Mantis
Difference of Antennae
Set of Wings and Flying ability
Counting of Abdomen Segments
Body Size and Length
Cannibalism Behavior
1.) Difference of Antennae
The morphology of antennae isn’t so prominent when the mantis is at the growing stage i.e. nymphs. It’s hard to distinguish whether it’s a male or female. However, as they grow older, the male’s antennae do not only grow longer than the female’s it also becomes relatively thicker.
If you take a closer look at a nymph perhaps you’d find the same difference in that the female possesses extremely thin thread-like antennae while the male’s antennae is thicker. Depending on the species, sometimes females have smooth antennae while the male’s antennae are thin hair-like. Smaller mantids have 18 to 20 mm long antennae whereas larger specimens have antennae that measures around 32 to 26mm.
The male mounts on the bigger female from her back.
2.) Set of Wings and Flying Ability
Although both male and female have wings, it’s only the male that can fly. Males must fly up to their mating partner during breeding season.
Although both male and female have wings, it’s only the male that can fly. Males must fly up to their mating partner during breeding season. Since males fly, their wings are longer than the female’s something that can be observed only when they become adults. The Hierodulatranscaucasica female possesses pretty long wings one that can cover all her body.
However the species may be, the male’s wings are either always up to the size of its body or bigger. It is one basic rule of a flight that is the wings must be at least bigger than the body. The female’s wings are just not big enough to lift their heavy weight. The Rivetinabaetica female has 19 – 24 mm long wings while the male’s wings measures around 40 – 42 mm in length.
3.) Counting of Abdomen Segments
Prominent among the differences between male and female praying mantis is their abdomen segments. Male has eight abdominal segments while the female has six. Male has all segments almost equal in size but the female’s segments are not. One of the female’s segments especially the last one at the end of her abdomen is probably the biggest.
The female mantis is eating its mating partner.
4.) Body Size and Length
The rule of thumb in praying mantis is that the female is always bigger than the male. The female reaches the overall length of 10 inches while the male measures around 6 to 7 inches. The male has relatively slender body while the females are fatter. Different species have different lengths estimating 96-105 mm, 54-70 mm and 32-38 mm.
5.) Cannibalism Behavior
Apart from structural differences, the male and female praying mantis exhibit different behavioral adaptations. The cannibalism is observed in female praying mantis while the males are almost entirely innocuous. Females likely cannibalize their mating partner right after the copulation. Scientists believe that females are usually too hungry to mate with the male. More so, they will prefer smaller males so they could easily eat them after mating.

Female praying mantis are always bigger than the males almost two to three inches greater in length. The female mantis isn’t only bigger it is also comparatively aggressive. Even so, female praying mantis are more likely to demonstrate cannibalistic behavior than the males. Sometimes when they are too hungry they might eat the male either during or after mating. Therefore, males sometimes approach the female from behind to get away with their cannibalism. Female mantises are also revered by people in different cultures.
Female Praying Mantis Facts
The length of the female praying mantis is about 10 inches with the weight averaging 4 to 5 grams. They have set of seven sternites each of which is clearly visible. Just to let you sternites are the ventral portion or abdomen of arthropods.
While most females are largely recognized by their green color some however exhibit gray appearance such as the Carolina mantis. The green color provides them perfect camouflage against predators as they can afford to sit atop tall grass without being noticed.

Female mantis do have wings but they can’t fly. Thus, it’s not up to them to look for males during mating season. Males typically fly and search the female by following pheromones that are released by the latter. It is also logical assume that females are relatively less mobile.
They will rear back with the forelegs in an attempt to thwart the predator with their mouths opened and so as the wings.
Adult females likely display a unique set of posture especially if they feel threatened. They will rear back with the forelegs in an attempt to thwart the predator with their mouths opened and so as the wings.
Depending on species, the female lays 20 to as many as 400 eggs. The eggs are laid in protective casing known as ootheca. They may lay eggs either directly on the plant or on the ground. Although the eggs are protected in a case they are eaten by a certain wasps.
Prominent among the female’s behavior is its cannibalism. It cannibalizes her mating partner and is most likely to choose smaller males. Since the female mates with multiple males the cannibalism behavior is something that they can’t avoid. Soon after copulation the female eats the male’s head first followed by its abdomen. Sometimes however they leave the dead male after beheading it.

Do you have any idea where do praying mantis live? Praying mantis are abundant throughout their range. They are found in the temperate and tropical rainforests of Southeast Asia, Africa, and South America. While they are adapted to thriving in just about every habitat, mantis are less likely prefer tundra climates and boreal habitats. This article is all about praying mantis habitat and its worldwide geographic distribution.
Where Do Praying Mantis Live in the World? – Praying Mantis Habitat Facts
The European mantis (Mantis religiosa) predominantly occurs not only in the southern Europe, it is also found in Asia, northeastern United States, Canada, Africa, to as far as Australia. Germany is home to two major population of European mantis. An isolated population likely inhabits Northern Europe.
Mantis generally thrive in just about every habitat but they fancy choosing tropical homes as against the temperate ones.
The mantisreligiosa mantis was introduced in Connecticut in the late 19th century yet the species is thought to be the state insect of Connecticut. Chinese mantids and the European mantis are probably the only species that occurs in different continents. All other mantis have limited range.
Mantis generally thrive in just about every habitat but they fancy choosing tropical homes as against the temperate ones. There are very few species inhabiting temperate habitats. Praying mantis do not live in tundra and boreal regions.
The primary habitat of a mantis consists of grasslands, tropical rainforests, secondary forests, and primary forests. They will make homes in warmer habitats but mantis can also survive in deserts, meadows, and open fields.
