Praying mantis are diurnal insects, which means they are active during the day. They have excellent eyesight and need daylight to be able to find and catch their prey.
In temperate regions like North America and Europe praying mantis go through a regular annual lifecycle. Eggs are laid late in the season, before the cold weather rolls in. These hatch the following spring, with the praying mantis growing throughout the spring and summer.
This means that praying mantis come out as the weather warms up in spring. However these praying mantis are tiny so may not be noticed by many people.
As the spring and summer wears on, a praying mantis moults several times, getting bigger with each moult. The end result is that praying mantis may be more visible in the summer due to their larger size.
In conclusion, while praying mantis come out in the early spring, they are most commonly spotted in the summer months when they have reached full size.

Do Praying Mantis Come Out at Night?
Praying mantis generally don’t come out at night. They rely on sunlight to be able to hunt, so coming out at night is no benefit to them.
Predators such as bats are well-known for eating fat, juicy praying mantis if they can be found. It is therefore safer for the mantis to hide away from view during the night. Thankfully, praying mantis tend to be well camouflaged and are capable of sitting still for long periods of time.
When the sun begins to rise the following morning the praying mantis then comes out to hunt or find a mate. An added benefit is that the temperatures tend to be warmer during the day, which praying mantis tend to prefer.
When Do Praying Mantis Lay Eggs?
Only adult female praying mantis lay eggs. In temperate regions praying mantis don’t reach adulthood until the summer months. July and August can be good months to find adult praying mantis.
Once they are mature a female praying mantis can begin to lay eggs. While she will need to mate with a male for the eggs to be fertile, some female mantis will still lay eggs even without mating. These are, however, infertile and so will not hatch.
Praying mantis are most likely to lay eggs in the summer months and into the early fall. A female praying mantis will continue laying eggs until either the weather gets too cold and she dies, or she is eaten by a predator.
When Do Praying Mantis Hatch?
In tropical regions with warm weather throughout the year praying mantis eggs may hatch at almost any time. In temperate regions like North America and Europe praying mantis eggs hatch the spring after they have been laid.
The eggs remain in “suspended animation” throughout the tough winter. The baby mantis inside the ootheca wait for the first rays of spring before they consider hatching. As the air temperature rises, so too do the number of potential prey items hatching out.
Spring is therefore the perfect time for praying mantis eggs to hatch because the weather is warmer and there are lots of other tiny insects around for them to eat.
Do Praying Mantis Die in Winter?
Most praying mantis living in North America and Europe die in winter. It is simply too cold, and there is too little food around, for a praying mantis to survive the winter.
While there may be the odd exception, these are very few and far between.
Things may be rather different in tropical countries, where the air temperature remains warm right throughout the year. Here mantis may live rather longer than in North America, assuming they are not eaten by a predator first.
