Li Qingzhao has a sentence cloud: I am only afraid of the Shuangxi ship boat, which cannot be moved and has many worries. Although the "ship" here uses the word "boat", it is obviously derived from "grasshopper". As Wang Niansun said in the "Jade Chapter": The ship, the boat also. The boat is called a sternwheeler, and the locust is called a grasshopper, and the righteousness is similar. Grasshoppers here refer to smaller locusts, which are used to describe small boats, which are extremely thin.
grasshopper
Grasshoppers or locusts, in the folk, mostly refer to insects such as grasshoppers, which are nothing more than different sizes, not precise concepts; however, if it is related to insect taxonomy, the three words grasshopper, grasshopper and locust are still necessary to say. All three belong to the orthoptera locust suborder, which can be collectively referred to as locusts or grasshoppers. Compared with the same orthoptera, the common feature of locusts is that the antennae are thick and short, and they are not as ethereal and slender as the ant antennae.
grasshopper
Locusts can also be divided into three categories: locusts, grasshoppers and grasshoppers. One of the smallest and most inconspicuous is the grasshopper, which is characterized by its small size and diamond-shaped shape, so it is also called the rhombus locust. The dorsal plate of the forebreast extends backwards, covering the entire abdomen. The forewings are small and scaly. No auditor. Tarsals 2-2-3. The little grasshopper that often dances with moths in the light is it. Grasshoppers are small, but quite stout, because their front thorax dorsal plate covers the abdomen, and the overall feeling is relatively "hard". In general, the body color of grasshoppers is dull, similar to dirt, and very low-key.
Raise locusts
The most common thing we usually see is the locust, the basic feature is that the front chest and dorsal plate do not extend backwards. The antennae are longer than the leg segments of the forefoot. Tarsals 3-3-3. The claw has a midrest. Spawning is in the soil. There are many kinds of this category, some large and some small, with different forms, and they are widely distributed, and there are almost everywhere in China. Common species in the north are cotton locust, East Asian flying locust, flower shin green striped locust, short-fronted negative locust and Chinese sword horn locust.
Cotton locust
Cotton locust, scientific name Chondracris rosea (De Geer, 1773), also known as the great green locust, male length 45 ~ 51 mm, female 60 ~ 80 mm, male forewing length 12 ~ 13 mm, female 16 ~ 21 mm, is the largest locust in the north and even in the country. The whole body is yellowish-green , and the species word rosea refers to the rose red at the base of the hindwings. In general, Kong Wu is powerful, its hind feet are particularly stout, and there are fine teeth on the outside, sharp as a knife, and it may have a bloody disaster when it is stepped on, so the folk call it "stepping down the mountain".
East Asian locusts
The East Asian Flying Locust, scientific name Loxusta migratoria manilensis (Meyen, 1835), is a subspecies of the genus Locust in the family Locustidae. Its male adults are 33 to 48 mm long and female adults are 39 to 52 mm long, slightly inferior in size to cotton locusts. The body color varies greatly, including social, scattered and intermediate types, with grayish yellow-brown (gregarious type) or green head, chest and hind feet (scattered type). This species is a migratory "omnivorous pest" that has its share in the fearsome locust plague in history, and now the situation has changed, it is the most common species of locust farming, and the crispy grasshopper is its destination.
The tibia green-striped locust, scientific name Aiolopus tamulus (Fabricius, 1798), is a genus of green-striped locusts in the family Pterophoridae. The male is 15–21.5 mm long and the female is 20–29 mm long, slender, dark brown to yellowish brown, with an "X" stripe on the dorsal plate of the forethia, and the lateral base and posterior groove area are often bright green and more vividly colored. It was very kind to see it, because the locust that chased in the grass as a child was probably it, and it was extremely impressive.
Short-fronted negative locust, upper male and lower female
Short-fronted negative locust, scientific name Atractomorpha sinensis Bolivar, belongs to the order Orthoptera Cone-headed locust family. The male is 21-25 mm long and the female is 35-45 mm long, with green or brown ii-shapes. Unlike the previous locusts, the short-fronted negative locust has a sharpened head and protrudes forward, so it is called "cone-headed locust", which my hometown generally calls "old flat". This kind of behavior is relatively slow, the ability to fly and jump is not strong, the female is particularly weak, coupled with a docile personality, is one of the favorite childhood playmates of rural children.
Chinese sword horn locust
Chinese sword horn locust, scientific name Acrida cinerea, orthoptera sword horned locust family. The shape of the sword horned locust is slightly similar to that of the short-fronted negative locust, both of which are sharpened heads, but the size is much larger than that of the short-frontal negative locust, and the adults are generally 30-81 mm long, the female is larger than the male, green or brown. In addition, the hind feet of the sword horn locust could not fold up like a short-fronted negative locust, and it was always arched like this. This species is also known as the Chinese grasshopper, the East Asian grasshopper, the grasshopper in the poetry of the ancients is mostly a two-pointed locust such as a negative locust or a sword horn locust.
Grasshoppers, the specific species is unknown
Finally, speaking of grasshoppers, the appearance of the grasshopper is similar to that of locusts, and its characteristics are: the antennae are shorter than the forefoot leg segments, and there is a small protrusion at the proximal end of the antennae. No auditor. The head of the grasshopper is not sharpened like a negative locust, but the face is as narrow and long as Li Yong, which looks a bit like a horse's head, so it is called "horse head locust" in some areas. Grasshoppers are less distributed in China, the species are poor, and they are mainly concentrated in the south.
Grasshoppers, the specific species is unknown
The above is a simple way to distinguish between grasshoppers, grasshoppers and locusts, do you remember? Remember to go to the children to show it!
