The East Asian migratory locust has two generations a year under natural temperature conditions. The first generation is called the summer locust and the second generation is the autumn locust. Under artificial breeding, three generations can grow in various parts of Shandong. The East Asian migratory locust has a sturdy body, a wide range of food, and strong adaptability. It takes about 7-15 days from hatching to young locusts, and then 35 days of breeding to become an adult. It takes about 50 days from egg to sale, so the time is short and the return is fast. Raising 10,000 adults can reach about 40 kilograms. At the current market price of 15-25 yuan per kilogram, the economic benefits are considerable, and the seeds only need to be purchased once.

A female locust can lay more than 60 to 120 eggs in its lifetime. The reason why migratory locusts are popular is that they have soft, tender meat and rich nutrition. According to expert analysis and determination: its protein content is as high as 74.88%, fat content is 5.25%, and carbohydrate content is 5.25%.

In addition, it is also rich in calcium, phosphorus, iron, copper, manganese, vitamins A, B, 18 kinds of amino acids and a variety of active substances.

The face is tilted backwards when viewed from the side, and the facial ridge is broad and flat, with a width between the bases of the antennae that is about 3 times the width of the first antennae. The compound eyes are small and ovate, with a longitudinal diameter of 1.5-1.6 times the transverse diameter, and are the same length as or slightly longer than the subocular groove. The antennae are filamentous, reaching the rear edge of the pronotum. The pronotum is broad and flat, with the widest part between the lateral ridges being much larger than the narrowest part; the length of the pre-groove area is longer than the post-groove area. The forewings are well developed, exceeding the top of the femur of the hind leg, and the wing top is broad and round. The cubital vein area of ​​the forewings is wide, and its widest part is 5 times the narrowest part of the midrib area. The top of the knee side piece below the femur of the hind leg is rounded. The supraanal plate is triangular in shape, with the middle of the lateral edge rolled up; the lower genital plate is conical; the coronoid process of the dorsal plate of the penis base is protruding upward, and the bridge is flat and shallow.

Females are larger and more robust than males. The top of the head is blunt, wide and short. The lateral fossa of the head is wide and flat with large puncta. The facial ridge is wide, and its width at the base of the antennae is about 4 times the width of the first antennae segment. The facial ridge disappears below the middle ocelli. The antennae are filamentous and do not reach the rear edge of the pronotum. The transverse groove behind the pronotum is straight, and the middle part protrudes slightly forward. The forewing slightly exceeds the middle part of the femur of the hind leg, and the wing top is narrow and round; the middle part of the subfrontal vein area is wide, and the elbow vein area is wide, about twice the width of the midrib area. The ovipositor is short and thick.

Body color: dark yellow-brown. There are light-colored longitudinal stripes on the side ridges of the pronotum. The hind wings are almost entirely dark brown. The inner lower side of the hind femur is red. There are three black horizontal spots on the inner side, and a distinct light-colored pre-knee ring on the outer side, with black knees.
