Praying Mantis Life Cycle

Life Cycle of a Praying Mantis And Other Intriguing Facts

The praying mantis got its name because of its unique style of resting with the forelegs joined together, as if in a state of deep thought or praying in front of a deity. Like its interesting style of resting, a praying mantis' life cycle is also unique.

Praying mantis is a carnivorous insect notorious for eating almost any living thing that comes its way. The body structure of a praying mantis is like that of most insects, which is divided into three parts―abdomen, head and thorax, and the antennae that are used for smelling.
Life Cycle
Praying Mantis
Life cycle of praying mantis starts with a unique, infamous and interesting method that is known as, 'sexual cannibalism'. In this method, the female kills or feeds herself on the male after mating. In some species of praying mantis, females eat the head of their mate after copulation. This is actually a topic of debate though many researchers deny the hypothesis. It is said that only 15% of praying mantis females consume a male after mating. Praying mantis lifespan varies with respect to different species, but the average lifespan of a praying mantis is almost one year. In most of the species of praying mantis, they live only 6 months as an adult. Summer season is the breeding season of the praying mantis. There are three stages in the life cycle of a praying mantis.
Eggs: After fertilization, the female lays 10 to 400 eggs in the autumn season. These eggs are secured on leaves, stems or any other safe surface. The egg houses are interesting, frothy, liquid-like structures present in their abdomen, called ootheca. It has a compartment-like special formation for every single egg. These compartments have a small one-way, valve-like structures that helps the insects to hatch with minimum efforts. These 'oothecas' are meant to protect the baby mantis during the cold weather.
Nymphs: The developed small-sized mantis come out of the oothecas in the spring season. The first meal of these small praying mantis is surprisingly, their siblings! These nymphs also eat flies, aphids, and small grasshoppers. These nymphs take the whole summer season to grow up to adulthood.
Adults: On reaching adulthood, the small praying mantis shed many layers of their exoskeleton, which is called molting. Below their exoskeleton are their growing wings.

The abdomen of the praying mantis is elongated. In adults, this area is covered with wings. The head is triangular with mounted compound eyes. The size and the color of the praying mantis varies according to its species. The colors range from faint green to faint pink, but most commonly, they are pea green or brown in color. Some praying mantis are pink in color, especially the species found on similarly-shaded flowers found in tropical regions. Praying mantis have very sensitive eyes that move in a 1800 angle, which enables them to see predators from a distance of 60 feet.

The praying mantis likes to stay in warm and humid regions. Hence, various species of praying mantis are found in North and South America, Europe, Southern Asia, Australia, and South Africa. There are more than 2000 species of praying mantises, with the smallest being 2/5 part of an inch and the biggest being 12 inch long. Most species are found in Asia, whereas about 20 species are native to the United States. Most of the species of flower mantis―a species of praying mantis―can make a perfect illusion of a flower, which confuses their prey which sometimes land on the back of the insect to collect the nectar. Camouflaging also helps the praying mantis to stay safe from numerous predators, like birds and bats.

The humble forelegs that gave this name to the praying mantis are actually extremely well equipped, with sharp spine like rows that help them to catch their prey. The praying mantis mimics the leaves and stems in a way which makes them almost invisible to their prey. When the prey is within the reach, they put their pincer-like foreleg forward and grab it. Most often, they start eating their prey when it is still alive. The prey of the praying mantises are usually fellow mantises, butterflies, beetles, spiders, grasshoppers, crickets, and almost all other invertebrates. Some species of praying mantis eat vertebrates like small frogs, mice, lizards and even hummingbirds.
Praying Mantis Facts

Praying mantises are diurnal insects, which means they work and hunt only during the day time.
They shed their exoskeleton (outer skin layer) for a record 12 times, before growing into a complete adult.

Praying mantises are useful insects for gardeners and farmers as natural insecticides. Hence, it is legal in the US to sell and keep only native praying mantis species.

When threatened by predators, the praying mantis stands tall with an open mouth, fanning wings and spreads out it forelegs to look bigger than their actual size in order to scare the opponents.

Praying mantises shed their exoskeleton (outer skin layer) for a record 12 times, before growing into a complete adult.
Preying Mantis
Some species of praying mantis never grow wings at all and those who have the wings fly only when the female mantis spreads the pheromones (chemical signals) to attract the male.
Praying Mantis Insect
An interesting fact, the praying mantis has only one ear, that uses the same ultrasonic frequency that the bats use, which are by far their biggest predators.
The praying mantis name is often misspelled as 'preying' mantis which is possibly because of their significant preying characteristics. It is always a fun to observe an insect and especially when it is the 'alien-like' triangular headed praying mantis.
