Parts of the bodies of insects

In Insect Identification 300 views

Insects are a diverse group of creatures that have the same main body parts, which distinguishes them as members of the Insecta class. All insects have six legs and a body divided into three segments called head, thorax and abdomen.

The head of an insect contains the parts of the brain and mouth, the antennae and the eyes. An insect either has parts to chew or suck on. The chewing parts in the mouth cut and crush the food. The sucking parts include a beak or proboscis, which the insect uses to pierce the plant or animal tissue and suck the fluid. A mosquito is a known example of an insect with suction parts. Butterflies and moths also have these parts, but instead of piercing the tissue, they suck the nectar. The bees have a combination of parts to suck and chew.

The eyes and the antennae are the two main sensory organs of the head. Antennas are used for touch, smell and hearing sometimes. Insects have two large compound eyes, which have a pair of individual targets. Each lens produces a separate image. Although the vision of an insect is not as clear and clear as ours, it is much better to judge distances and detect the slightest movement.

The middle segment of the body of the insect is called the thorax. It is divided into three smaller segments, each having a pair of legs. All insects have three pairs of legs that can take many forms. The front legs can be designed to capture prey or dig. The hind legs are sometimes modified to jump or swim. Some insects, such as grasshoppers, use their hind legs to make sounds.

Most insects have two pairs of wings attached to the thorax, although some have only one pair and others have no wings. The front wings of a beetle have been modified into a shell that covers the body and the hind wings are used to fly.

The abdomen is usually the largest part of the body. It is divided into 10 or 12 segments, and each segment has a pair of spiracles that are used to take air. Aquatic insects breathe through gills or reach the surface in search of an air bubble that they carry under their wings or in the abdomen. The organs for mating and laying eggs are near the end of the abdomen. Insects also have a pair of sensory appendages called fences at the end of the abdomen. The earwigs have large fences that look like pincers, while many other insects have fences so small they are difficult to see. Some insects also have hearing organs in their abdomen. Some insects, like crickets, have them on their legs.
