History of growth and development of flies and ants

One day, the ants met the flies.

At that time, the flies were stealing food from a house, while the ants were busy looking for food. So, the fly laughed at the ants: "You guys are so busy every day, and the results are not so little things?"

Besides, what is the use of your accumulation of these things? Look at me, you don't have to worry about eating all day long, you should learn from me! ”

Flies," replied the ants, "you are the object of disgust, the source of the spread of disease." Let's bet you won't end well in the winter! ”

Hmph, if you don't listen to me, forget it, you're tired of it! ”The fly muttered to himself haughtily, glad he wasn't like an ant

Winter is coming, snowflakes are flying all over the sky, and the flies are dying of starvation because it is frozen and cannot fly.

Brother Fly, do you remember me? A familiar sound reached the ears of the flies. It's the ants! They're eating next to the flies!

Flies, you're throwing in the towel this time! Food that doesn't need to be earned by hard work is earned without hard work! The ant said earnestly.

At this time, the fly had no strength to reply, and it finally died of hunger and cold.

And the ants are happily eating at this time!

After learning the characteristics of insects, some students have doubts in their hearts: since the characteristics of insects need to have two pairs of wings, so if an ant does not have wings, should it not belong to insects? In response to your questions, please take a look at the information above

Ants are a common insect that lives in groups, and there are many types of ants, each of which is divided into female, male, and worker ants, and the soldier ant is a variant of the worker ant. Both females and males have wings, while worker and soldier ants do not have wings. Ants have a very mixed diet, most ants will dig the soil to build nests, and can store food, in winter they hide in the nest in a dormant state for the winter, some species of ants do not sleep, in the active state of winter.

Ants are very closely related to humans, some species are harmful to humans, and some species have a beneficial side to humans, but in general, there are more harmful and less harmful in places where humans live, and they need to be controlled. Flies only have one pair of wings! There is also a pair that has degenerated into a balance bar, which should not be considered wings!

Ask the students to recall the common characteristics of the insects mentioned in class:1The body is divided into 3 segments--- head, chest, and abdomen 2

With 3 pairs of legs and 2 pairs of wings on the chest, it seems that ants and flies do not meet all the characteristics of insects, so are they not insects? Please remember that animals in nature are diverse. When we talk about vertebrates, are there some special animals that don't fit their characteristics exactly?

Ants are insects, insects belong to the category of arthropods. All arthropods have a hard body shell or exoskeleton for protection. The adult has a head with a pair of antennae, eyes, and a set of mouthparts, and a thorax with three pairs of legs and usually two pairs of wings.

When it comes to ants specifically, only the king and queen ants have a winged stage, and it is not for life. By the same token, even if a fly has only one pair of wings, it is still an insect.

An ant can move something ten times heavier than it.

The strength of the ant is actually the relative strength that manifests itself due to the small size of the insect. The size of an animal's muscle strength is directly proportional to the size of its cross-section, that is, it is proportional to the square of its length, while the volume and weight of the body are proportional to the cube of its length. The size of an animal's muscle strength is directly proportional to the size of its cross-section, that is, it is proportional to the square of its length, while the volume and weight of the body are proportional to the cube of its length.

As a result, the relative strength of the muscles increases as the body decreases. As a result, the relative strength of the muscles increases as the body decreases. The huge negative gravity on the surface of ants is mainly due to their small body.
