Mantids

The praying mantids – mantis really refers only to the genus Mantis, while mantid refers to the entire group – are an order of insects (Mantodea) that appear to be “praying” when their front legs are held at rest. These long, narrow insects have a distinctive appearance with the large, characteristic raptorial (folded back like a pocket knife) front legs modified for grasping prey, with long, sharp spines (that fit into grooves on the opposing parts when not in use) for holding what they catch. They also have an elongated thorax that functions like a neck, enabling the triangular head with its large, compound eyes to swivel almost all the way around. Walking sticks might be confused with mantids, as they, too, are long and thin, but they do not have raptorial front legs.

Biology
Female mantids generally are larger than the males and have a stouter abdomen. It is commonly believed that the praying mantid female eats the male’s head during the mating process, but this only happens occasionally in the wild unlike in captivity. After mating in the fall, the females lay numerous eggs (dozens to hundreds, depending on the species and conditions) in a frothy secretion attached to a plant stem that hardens into a stryofoam-like egg case (an ootheca). The adults die a few weeks later.
The eggs overwinter within the egg case and hatch in the spring into a very small version of the adult. Although they resemble the adult, the nymphs may be a different color or pattern.

Incomplete metamorphosis development:

As they go through incomplete metamorphosis over the course of the growing season they grow in size, eventually developing wings as they reach the adult stage in late summer or fall. They tend to be clumsy fliers, and rarely are seen in flight.
