As for the 10-segmented abdomen, it also strongly stretched or, conversely, very extended and has a sheet-like shape. Because of these structural features of the body have phasmatodea may accept or rod-shaped or leaf-shaped. From talking about stick insects and listovidkah.
Currently, there are about 2,500 species phasmatodea distributed mainly in tropical countries. The vast majority of them has a rod-shaped. Mostly protective paint, which can be green, brown or gray.

It is found that the decisive influence on the coloring stick insects have luminous stimuli coming into a specific area of the eye. Stick insects darkens and lightens in response to other stimuli, such as temperature change and humidity, changes in osmotic pressure of blood and even mechanical action.
When this color change is caused by contraction or expansion in a lump pigment grains present in the hypodermis. In some cases, stick insects observed very rough sculpture covers, the body can be sharp shipoobraznye growths.
Some stick insects along with the protective coloration, masking all the visible parts of the animal sitting motionless, observed demonstrative on those parts of the body, which alone are hidden.

In cases where the elytra completely or almost completely absent, that part of the rear wing, which folded at the top, forming a special Krylov plate having a protective coloration, and thus is protective elytra. Almost all of the stick insects fly well, and because of the painted wings on display only during the flight.
Stick insects lay their eggs on any surface, depending on what is selected as bedding. It is important to try to protect the eggs from the mold, which often happens, if the ground is too wet. Oblong-shaped egg is enclosed in a special capsule having a cap, which raises the larvae at hatching.
Externally, the eggs may resemble seeds. Larvae hatch from them are very similar to adults and differ from them primarily in size and somewhat longer legs and antennae. Before we reach adulthood, they undergo up to 6 molts. Lifestyle larvae is the same as in adults.
The life of these amazing insects depends on the conditions and ranges from 8 to 15 months, but as they multiply, gradually there is a change of the population.
