What are the distinctive characteristics of grasshoppers?

Grasshoppers, also known as grasshoppers, are called "grasshoppers" in this province: usually green, brown or black, with large heads and short antennae; The front chest backboard is hard, extending to the left and right like a saddle, and the middle chest and back chest can't move when they heal. Jiao Da, especially its hind leg muscles are short and strong, and its exoskeleton is hard, which makes it an expert in jumping. The tibia has a sharp saw and is an effective defensive weapon. The ovipositor has no obvious protrusion, which is the biggest difference from the owl. Eating habits: like to eat fat leaves, such as sweet potatoes and water spinach, abnormal: not completely abnormal.

After mating, the female locust inserted the oviposition tube into the soil with a depth of 10cm and laid about 50 eggs.

When laying eggs, the female will secrete white material to form a cylindrical plug, and then lay eggs.

This is an egg that has been developed for 19 days; At about 24℃, locust eggs can hatch in about 2 1 day. The hatched nymph crawls out of the soil. At this time, its appearance is very similar to that of adults, except that it has no wings and its body color is lighter. Nymphs look more like adults in the first year or two, but their heads and bodies are out of proportion. Winged buds grow at the third age, which is obvious at the fourth age. When the nymph is five years old, it will climb to the plant and hang for a while, and then the adult will come out. (Morphology and living habits): Both adults and larvae of grasshoppers can chew the stems and leaves of plants with developed chewing mouthparts.

Adult hind limbs and legs have a series of papillae equivalent to elastic devices, and the base of radial vein of anterior wing has thick vein equivalent to chordae tendineae device. When they rub, the vibrating area of the vibrating wing can make sound, which is their sounder. The auditory organs of locusts are also very special, located on the side of the first abdominal segment.

Grasshoppers are commonly known as "grasshoppers" and are called "grasshoppers" in Taiwanese. Their life history is egg e nymph e adult, which belongs to incomplete metamorphosis. Chewing mouthparts are herbivorous insects. Most of them are not picky eaters. In weeds, they can often be seen eating the leaves of Gramineae plants. Its tentacles are not as long as those of the owl, and it is a short whip, but its hind legs are strong and it can avoid natural enemies by bouncing. Sometimes you can see wedding photos of two locusts.

Ecological habit: Oxytropis Oxytropis is a very common locust in flat land and low altitude areas, which can occur for two generations a year.

The reason why locusts move in groups is mainly because they need high temperature to stay together for warmth.

Adult hind limbs and legs have a series of papillae equivalent to elastic devices, and the base of radial vein of anterior wing has thick vein equivalent to chordae tendineae device. When they rub, the vibrating area of the vibrating wing can make sound, which is their sounder. The auditory organs of locusts are also very special, located on the side of the first abdominal segment. According to the living habits of locusts, they can be divided into migratory and non-migratory types. These two kinds of locusts are very threatening to crops, especially the former is very destructive. As long as they cross the border, all green plants will be eaten up. The shock caused by the plague of locusts is really flattering. Its diet is very diverse, eating all kinds of green plants, especially Gramineae plants.

Nymphs, also known as locusts, look like adults, but only have wing buds and are good at jumping. After four or seven skinning, they will become adults who are good at jumping and flying. Some locusts have short antennae and short ovipositor tubes. At present, there are about 5000 kinds of locusts in the world. The longest part of a locust's body is its hind foot, which is almost the same as its body length. It can jump out of its body eight times as long in one jump.
