This insect is quite large, reaches a length of 11-12 centimeters. The head of the praying mantis resembles a triangle with well-developed eyes.
Sharp vision helps the insect react with lightning speed to prey, which is served by smaller insects. The praying mantis can be called a chameleon. After all, he is able to change color in accordance with his habitat. For example, an insect can mimic the color of fallen leaves or bright green grass.
Mostly people see green praying mantises, as most often insects lurk on trees or in bushes. They are so motionless that it is difficult to notice them. They discover themselves during the flight. It is noteworthy that only males fly. Females only occasionally flutter from one branch to another.
These insects are quite harmless, but their large size and unusual appearance scare people. Perhaps that is why in the media you can find the phrase: "Praying mantises attacked Moscow." In fact, they are harmless. The inhabitants of the Caucasus and Crimea have not been surprised by these insects for a long time and consider them to be ordinary representatives of cockroaches.

In addition, the invasion of praying mantises in Moscow and its region can be attributed to the fact that over the past 5 years the number of intercity transportation by freight transport has increased.
Insects can come to a large city from the southern regions on these trucks, and then amaze local residents and guests with their appearance. Finally, it can be assumed that a couple of praying mantises are able to escape from the terrarium of an exotic lover and roam the streets of Moscow.
