what are insects

Insects are the largest group in the animal kingdom. Scientists estimate the number of a million species of insects on the planet, living in any possible environment from volcanoes to ice. Insects help us pollinate food crops, break down organic matter, provide researchers with the keys to cancer treatment, and even solve crimes. The insect can also harm humans by spreading diseases and damaging plant composition.

How are insects classified?

Insects are arthropods. All animals in the arthropod division have an exoskeleton, a segmented body and three pairs of feet. The arthropod sects include: arachnids, millennials, and harps.

The insect population includes all insects on Earth, often divided into 29 ranks that have the same physical characteristics as insects and are therefore classified together.

Some taxonomists classify insects differently, using evolutionary connections rather than physical characteristics. In order to identify the insect, it is useful to use the 29-order system, so that you can identify the physical similarities and differences between the insects you notice.

Here is an example of a classification of royal butterfly:

  • Animal Kingdom
  • Arthropods Division
  • Insect class
  • Wing hospitals rank
  • The Family of Nymphs
  • The race of the Danaus
  • Plexipas type

The name of the gender and gender is usually combined together to express the scientific name of an individual. The type of insect may be spread in many regions and has many names in many languages ​​and cultures. But the scientific name is the standard name used by entomologists around the world. This system is called binary naming.

Simple dissection of insects

As you remember from elementary school, the simplest definition of an insect is that it is an organism that has 3 pairs of feet and 3 areas of the body – head, chest, and abdomen. Some entomologists may add a pair of sensors (sensing pods) and the outer oral portion. With some exceptions to this general description.

Head area

It is the front of the insect’s body and contains the mouth, sensors and eyes. Insects have a mouthpiece designed to help them feed from various things. Some insects drink succulents and have modified oral parts in the form of a tube called a hose to suck the fluid. Some species have an oral part to chew and eat leaves or other plants, some can bite, others absorb blood or plant fluids.

The pair of sensors have clear parts that resemble fur. They appear in multiple forms and are a hallmark of insect identification. Sensors are used to sense sounds, vibrations and other environmental factors.

 Chest area

It includes the chest, or the middle area of ​​the body, wings and feet. Six feet stick to the chest. The chest also contains the muscles that control movement. All insects contain five parts. The feet can appear in different shapes and have different adaptations to help the insect move in its place of life.

For example, locusts have feet designed to jump, while bees have feet that have special baskets to hold pollen while bees move them from one flower to another. Wings appear in different shapes and sizes and are another distinctive sign that we recognize an insect through.

Butterfly and moth have wings made of overlapping scales, often in bright colors, while the wings of some insects appear transparent, with only a network of veins showing their shape. During rest, the beetles and the mare insect keeps its wings folded and flat on its bodies, and other insects keep its wings vertically, such as butterflies and tremors.

 Abdominal area

It is the last area of ​​the insect’s body and contains the vital organs of the insect. It has digestive organs, including the stomach and intestines, to absorb nutrients from food and separate waste. The sexual organs of the insect are also present in the abdomen, and the glands that secrete the pheromones that characterize and prepare the insect to attract the sexual partner in that region as well.

Let’s take a closer look at insects

The next time you see a ladybug or a moth in your area, come closer and take a closer look. See if you can recognize the head, chest and abdomen.

Look at the shape of the pods and see how the insect shows its wings. These signs will help you learn about the insect puzzle and provide you with information on how it lives, how it nourishes.
