From Egg to Adult: The Praying Mantis Lifecycle

by Sarah

From Egg to Adult: The Praying Mantis Lifecycle? Praying mantises are fascinating creatures. They have an interesting life cycle that goes from egg to adult, and they’re also a great insect for people to keep as pets.

In this post, we will take you through the praying mantis life cycle step by step so you can get a better understanding of what these creatures go through in their lives.

All About the Praying Mantis Lifecycle

Our Praying Mantis lifecycle diagram will help you follow along, but 

Praying Mantis Egg

The praying mantis starts as an egg. A female mantis can lay anywhere from 30 to 150 eggs at a time, depending on the species of praying mantis and how much food there is available for her. The eggs are usually laid in clusters or lines so that they’re easy to find when it’s time for the mother to leave.

The eggs are a pale color and have a coating of slime on them. The female praying mantis will lay her eggs in the late summer or early fall, when it’s warm enough for the babies to survive but she knows that they won’t hatch until springtime. Once laid, the mother leaves immediately without looking back. She has done her duty and will not live to see the praying mantis babies hatch.

Praying Mantis Nymph

It takes about three months for the eggs to hatch. Once they do, a new praying mantis emerges from its egg and hangs there in a cocoon-like sac that is more like an upside-down pocket than anything else.

The newly hatched baby will often stay close to where it was born as it grows larger over the course of about two more weeks. At this point, the nymph is now large enough to eat some soft-bodied insects and other small prey items like aphids or even smaller praying mantises if they are available.

Praying Mantis Young

This stage finds them larger than a nymph, but still not full-grown.. They are about three inches long and have grown wings.

Under the right conditions, they will live to mate in their adult form if they survive this stage of life. If not, then all their eggs die with them unless another praying mantis eats them before that happens.

Praying Mantis Adult Female

The female is larger and more colorful than the male praying mantis. She’s about six inches long as an adult, while males are only four to five inches in length.

Praying Mantis Adult Male

The male is smaller and less brightly colored than the female of this species because he does not need to attract a mate for reproduction purposes. This is pretty much the opposite of most animals you will study. He only reaches about four to five inches in length.

How long do praying mantis live after laying eggs?

Motherhood is tough, apparently. The female mantises usually die around two weeks after they lay their eggs. 

Whew!

How long does a praying mantis live in general?

Praying mantises live anywhere from a few weeks to over a year, depending on the climate.

In most parts of North America and Europe, praying mantises live about six months at best after they have laid eggs (that point in their life cycle). During this time, she may hunt for food or just lay around until it is time to lay eggs.

Some praying mantises live much longer in warmer climates like South America and Africa, where they have a life cycle of up to one year.

The longest I’ve heard of is two years – this was an accidental discovery in New York City when the mantis populations were high due to urban heat islands from buildings

Praying Mantis Food

What do they eat? That is a great question! The praying mantis has a diet of spiders, flies, and other insects. Um, except for one other little fact.

They also have different mating rituals, mainly because the female is larger and can eat a male if she feels threatened by him or wants his food for her eggs.
