Growing up, I always thought of Praying Mantis as fascinating creatures. From their praying appearance to their amazing body shapes, colors and the ability to camouflage with their surroundings.
A few days ago, I saw this Praying Mantis hanging onto a grate of chicken wire, while overlooking an ootheca (its egg case). In the past I spotted numerous oothecae around the garden, thinking they were some type of chrysalis. Now I now the case holds Mantis eggs.
Last week, my daughter spotted a green Praying Mantis on a fence panel and noticed something attached to its derriere. Upon closer inspection, we realized it was a female mantis laying eggs and we were fascinated by the way it crafted its egg’s case (see the video below).
Praying Mantis Laying Eggs (Video)
The female mantis produces between 100 to 400 eggs in a frothy liquid case to protect them from microorganisms, parasitoids, predators and harsh weather. In the Spring, nymphs/young mantises emerge from the egg case and begin eating voraciously to grow fast into adulthood. Many of them do not survive as they tend to eat each other to survive or are eaten by predators.
The adult mantis continues to eat and grow; and during this time it will shed its outer skin, a process known as molting. Between late Summer and Fall, the adult female will attract a male mate and after mating, a new life cycle will begin. Similarly to grasshoppers, it is said that Praying Mantis die shortly after laying eggs.

Why do female mantises eat the males after mating?
The males self-sacrifice themselves for their offsprings. Males have been found to have nutrients such as proteins and lipids and by cannibalizing the males, the females may produce eggs of greater energy density. The bodies of the ill-fated males are used to aid their production.
