What are Insects?

There are many kinds of insects and different forms. They belong to arthropods in invertebrates. They are the largest animal group on the planet, accounting for more than 50% of all biological species (including bacteria, fungi, and viruses). Every corner of the world.

Coleoptera

A pair of antennae, usually with two pairs of wings and three pairs of feet. The number of insect antennae, including the number of antennae rods, is often the basis for identification ^[3]

Temperature is the most important factor that determines the growth and development rate of insects. Climate warming can accelerate the development of various insect states, leading to
The migration period and population peak period are advanced ^[1]

Insects communicate with the external environment through the nervous system. The nervous system connects the surface of the body wall with a variety of sensors and reactors. The insect's nervous system is also an insect's information communication system and an important overall control system

The insect's digestive system can be divided into foregut, midgut and hindgut.

There are three main types of insect pronunciation:

First, flight, feeding, courtship activities.

Humans can hear vibration frequencies of 20 to 20,000 Hz. The butterfly is 7 to 13 Hz; the fly is 147 to 220 Hz; the vibration frequency of mosquitoes flapping wings is about 594 Hz; therefore, we can hear the sound of flies and mosquitoes flapping wings.

Second, the body hits other objects.

In the world of insects, many insects have incredible abilities. For example: a small flea, struggling to leap, can actually exceed 200 times its height. There are also slugs and locusts, and their jumping ability is also excellent. Even more surprising is that ants can lift objects that are 52 times their own weight. Even butterflies that look slender, like migratory birds, can fly hundreds of meters or tens of thousands of kilometers in a row, or even longer.

The reason why insects have such amazing power is that they have particularly developed muscle tissue. According to scientists' research, the muscles of insects are not only special in structure, but also in large numbers. For example, humans have more than 600 muscles, while Lepidoptera insects have more than 2000 muscles. In addition to the insect's muscles, they can also help to fly long distances in addition to high and long jumps. For example, dragonflies, butterflies, bees, moths, etc., can fly far away because of the muscles that connect the wings between their chests and backs.
