Physiological characteristics and lifestyle of grasshoppers:

Grasshoppers, insects, also called locusts, have many species, have hard mouthparts, narrow and tough front wings, broad and soft hind wings, are good at flying, have well-developed hind limbs, and are good at jumping. They mainly harm plants in the Gramineae family and are pests.

Grasshoppers are good at maintaining their gregariousness and often live in groups. Female grasshoppers usually choose hard soil with considerable humidity and direct sunlight to lay their eggs. They often lay eggs in large numbers. They need a higher body temperature to promote and adapt to the active physiological functions.

1. Physical characteristics of locusts

The locust has a hard exoskeleton on its body surface, which is mainly used to protect and support the soft organs inside and prevent the evaporation of water in the body. This is one of the characteristics of adapting to life on land. The exoskeleton cannot grow with the growth of the locust's body, so the locust has to shed its skin many times during its growth and development.

2. Body Parts of a Locust

The locust's body is composed of many segments, and the whole body can be divided into three parts: head, thorax, and abdomen. The thorax is divided into three parts: prothorax, mesothorax, and metathorax. The abdomen has a total of 11 segments.

The morphology of locusts

1. Head - sensory and feeding center: The main structures of the head are antennae, eyes and mouthparts

Locust head

Antennae: 1 pair, filamentous, segmented, sensory organs, used for touch and smell. Eyes: Locusts have 1 pair of compound eyes and 3 simple eyes.

Compound eyes: Located on the upper part of the head, one on each side, they are relatively large and composed of many small eyes. They are the main visual organs.

Ocellus: One is located between the compound eyes and the antennae, and another is located in the upper center of the front of the head, forming an inverted isosceles triangle with the other two ocelli. Ocellus can only sense light.

Mouthparts: They are the feeding organs of locusts. The mouthparts of locusts are composed of 5 parts, including 1 upper lip, 1 lower lip, 2 upper and lower jaws, and 1 tongue. The upper jaw is very hard and suitable for chewing. It is the main structure for cutting and chewing plant stems and leaves.

2. Thorax - Movement Center: It is divided into prothorax, mesothorax and metathorax. There is a pair of legs on each of the prothorax, mesothorax and metathorax of the locust, which are called forelegs, mesothorax and hindlegs respectively. The legs are segmented, and the hindlegs are well developed and suitable for jumping, which are called jumping legs. There is a pair of wings on each of the mesothorax and metathorax of the locust: forewings and hindwings. The forewings are narrow and leathery, covering the hindwings for protection; the hindwings are wide, membranous and soft, often folded under the forewings, and unfolded during flight, which are organs suitable for flying. 3. Abdomen: The abdomen of the locust is composed of 11 body segments. ① On both sides of the first segment of the locust's abdomen, there is a semi-lunar membrane, which is the locust's auditory organ. ② There is a small hole on the corresponding positions on both sides of the mesothorax, metathorax and the first to eighth segments of the abdomen of the locust, which is called the spiracle, and there are 10 pairs of these holes. The spiracle is the gateway for gas to enter and exit the locust's body, and gas exchange is completed through the trachea and tissue cells.
