Praying mantis are magnificent creatures. They come in many different shapes, sizes, colors, and behaviors. They live all around the world and have adapted to every habitat they live in. Some mantis look like leaves, others camouflage between flowers, and some look like grass and are basically invisible to their prey. Depending on the species and their habitat the lifespans of the praying mantis can vary a lot. 

As a whole, the lifespan of a praying mantis highly depends on the species and their habitat. Some praying mantis species only live for several weeks, while others can live up to 18 months. 

The Lifespan of a Praying mantis

A praying mantis goes through various molts throughout its lifetime. In general, male praying mantises have a shorter life than females.

This makes sense because after the males were able to mate with a female, they are basically not needed anymore, while the female still has to develop and lay the eggs.

Every praying mantis goes through several molts. Male mantis molt 7 times, while female mantis molt 8 to 9 times. When a baby mantis hatches, they are called “L1” or “First instar”. After the first molt, they are referred to as “L2” or “Second Instar” and so on. Most insect species are categorized in these development stages.

The time periods between these molts differ from species to species.

Different Praying Mantis Species

The praying mantis species include more than 2000 different species, that are categorized in several families. Some of these families are:

  • The Genus Deroplatys, better known as Dead Leaf Mantis. One example would be Deroplatys Desiccata, one of the biggest praying mantis species.
  • The Genus Eramiaphila or also referred to as Desert Mantis
