Praying Mantids


These insects get their name because they have very long front legs that they hold in a position that reminds people of praying. There are about 1,800 species of praying mantids around the world. People often refer to any mantid as a praying mantis, but mantises are part of a smaller group within the mantids. Praying mantids are carnivores, eating mainly insects and other small animals. Many gardeners and farmers welcome mantids, because the insects they eat are often pests that hurt crops. In addition to insects such as crickets and grasshoppers, mantids eat spiders, frogs, lizards, and even small birds.
Praying mantids have long necks topped by a triangular head. They can turn their heads 180 degrees—an entire half circle—which, along with exceptional eyesight, helps them spot prey. They're well-camouflaged, adapting colors that help them blend with the plants they live near. Some also have amazing body shapes that make them look like leaves or branches. 

To hunt, mantids either sit and wait for an insect to pass by, or they stalk them. They're nearly invisible when they sit still, looking like part of a leaf or stem. When they are close enough, they strike so quickly—about one-twentieth of a second—you probably couldn't even see it happen. It's just a blur of motion. Their front legs have rows of sharp spines to help them hold on to their prey, which they usually begin to eat head first!
FAST FACTS
The scientific name of the order of praying mantids is Mantodea.

Most species, or kinds, of mantids live in tropical areas of the world. Africa has 880 species, while only 20 species live in North America.

On average, mantids live for about a year.
Most praying mantids have wings and can fly.

Most mantids range in length from 0.5 to 6 inches (1.2 to 15 centimeters). There is a species of mantid in Asia though that can reach 10 inches (25 centimeters) long. Female mantids are generally larger than the males of their species. When a pair of praying mantids mate, the female sometimes chomps off the male's head. Some scientists think that this source of food gives the female a boost of energy to produce her eggs. Mantids lay eggs in a frothy substance, which turns into a hard case that protects the eggs. Females lay their eggs in the fall, and the eggs can survive through winter in these cases.  When a mantid hatches, it looks like a miniature version of the adult, without wings. (These grow later.) Sometimes a young mantid's first meal is one or more of its siblings!

There are three main parts of a mantid's body: the head, the thorax, and the abdomen. Part of its thorax looks like a neck. While mantids are predators, they also have enemies that eat them. Bats, rodents, birds, frogs, and spiders eat adult mantids.
