 Description of migratory locust insects

 The length of the entire locust is about 5 cm, while the female is slightly larger than the male before sexual maturity. Its color is reddish and turns yellow during puberty. The front wings are characterized by the presence of small brown squares. The first thoracic ring bears three gutters, while the hind wings are transparent.

  the color The insect :is brown in its first stages, then turns orange with black parts as it grows. While the adult insect's color becomes reddish before puberty, then becomes yellow at sexual maturity, and these colors are more apparent in the males of these insects than in the females.

 These insects are characterized by the fact that they reproduce far from the places where they invade and feed. As for the place where they lay eggs, the insects grow and feed until they reach the stage of the full insect.

 The phenomenon of migratory or migratory locusts

This is a result of the high and dense numbers of insects that feed voraciously, and their movements become active with the rise in temperature, which leads to crowding of individuals in their places of presence, lack of food, and lack of grasses on which they feed, which leads to them gathering in very large and large numbers, so they work to form groups and fly in a circular manner above the rest of the individuals. Some of these insects fly with them, and the number of flying insects increases, and they travel and migrate to places full of food and vast green spaces, causing widespread losses. They may cause the loss of the entire green area and eliminate it. They may migrate from one continent to another, or from one country to another. They move very quickly during the day. If its group moves and flies in a certain direction, the rest moves behind it, creating the phenomenon of nomadism
