First, the difference between grasshoppers and grasshoppers
1. Grasshoppers, commonly known as grasshoppers and grasshoppers, belong to ORTHOPTERA, short-horned suborder (Acridoidea), including Acridoidea, Acridoidea and Acridoidea.
2. In daily life, grasshoppers or grasshoppers are generally called round-headed grasshoppers (generally referring to oriental migratory locusts and Asian migratory locusts), while grasshoppers with sharp heads are called grasshoppers (such as Chinese horned locust and short-fronted negative locust).
2. Introduction of Acridoidea, Tetrigoidea and Primordinae
1, Acridoidea
(1) Acridoidea can be divided into Acridoidea, Acridoidea, Acridoidea, Acridoidea, Acridoidea, Acridoidea and so on.
(2) Adults are medium and large, relatively stout. The head is short and the back of the head is retracted into the chest. Compound eyes are well developed, usually 3 single eyes. Antennas are shorter than the body, longer than the front foot and thigh joints, and are filiform, sword-shaped or mallet-shaped. The front chest backboard is developed, covering the middle chest backboard, and it is nearly saddle-shaped. The hindfoot and leg joints are particularly developed, the tibia joints are long, and there are 1 rows of thorns on both sides, 3 hocks, and 3 pads on the ventral surface of hocks. Most species have two pairs of developed wings, and a few species have short wings or no wings. The front wing is long and narrow, and the rear wing is membranous and often colored. Tail beard is short and small, not segmented.
2. Tetrigoidea
(1) Tetrigoidea (Acridoidea) includes Tetrigoidea (Acridoidea) and Acridoidea.
(2) The back plate of the chest is particularly developed, extending backward to the end of the abdomen, with a diamond-shaped tip at the end, hence the name locust. The front wing degenerates into scales, the rear wing is developed, the hock type is 2-2-3, and the middle pad is missing between the claws. The phonograph and audiometer can jump but can't fly.
3. Head General Division
The top of the head bulges like a horse's head. Antennas are shorter than the head, the left and right maxilla are almost asymmetrical, and the molars are thick. Most of the tarsal joints are 3 joints (but there are no 4 joints), and there are often a series of sound teeth inside the femoral joint of the hind foot. There are often auditory devices on both sides of the abdominal base plate.
