What are the mysteries about insects? What are the secrets of insects?

The secrets of insects are as follows:1. Insects are the earliest animals on earth.

Insects were the first animals to appear on Earth, and they lived on our planet as early as 400 million years ago. Since its birth, insects have survived five large-scale earthly disasters and are still alive today, and their vitality is more tenacious than that of Tyrannosaurus rex.

2. Industrious bees.

Currently, there are about 20,000 species of bees in the world. To produce 500 grams of honey from a single bee, it needs to fly back and forth between the hive and the finch flowers 10 million times.

3. High-yielding and long-lived cockroaches.

A female cockroach lays more than 2 million eggs a year. In addition, a cockroach can survive for nine days after being decapitated.

4. An astonishing number of insects.

The total weight of insects eaten by all spiders on Earth in one year far exceeds the total weight of living humans in the world.

5. A wide variety of spiders.

There are currently 35,000 species of spiders known to science, and new species are being discovered all the time.

1. Dry mud wasps: They like to nest in moist and warm places. They often build their nests in chimneys, where the temperature is suitable for the dry mud wasp to survive, but the young of the dry mud wasp often suffocate, so the dry mud wasp will build their nest in the wide chimney.

2. Fireflies: In appearance, it has six short legs and likes to use them for walks. When the male firefly is fully developed, they will grow wings because it is a beetle itself, and the female firefly will be in a larval state for the rest of its life.

3. Crickets: When choosing where to live, they don't choose naturally formed hidden places because these holes don't fit. They were all built in a hurry and without security.

They usually choose well-drained, sunny places, and when choosing these places, they have to build them themselves. 4. Grasshopper: strong feet, big belly and good jumping.

Found in wild grasses, low forests, and shrubs, often hiding in grass, or crawling, perching, and foraging on plant stems. It mainly eats the stems, leaves, melons, and fruits of plants. 5. Scarab:

Also known as the scarab, it is one of the largest and most well-known dung dung dung eaters. There are six fine-pointed teeth in front of the crescent-shaped parietal shell, which are not only digging tools and cutting tools, but also forks for inserting, lifting, throwing and throwing non-nutrient plant fibers in the manure material, and can also be used as a rake, bringing all the delicious things over. 6. Praying mantis:

With a wide green wing, a pair of front paws raised to the sky in a prayer gesture, but this sincere prayer hides its cruel customs. The pair of arms held high were actually its terrible **, its tools to prey on the gray locusts and white-fronted mites that passed by it. The sharp weapon strikes at the prey, so that the opponent has no power to parry, and even spiders and other insects are afraid when they see it, and become its food.

7. Cicadas: In the hot summer, people can often hear the cicadas, but no one may know that the cicada goes from eggs to larvae, and then becomes the singer of summer, and it has to hide in the burrow for 4 years. It has to go through the calamity of nine deaths and a lifetime before it can achieve positive results.

However, the singer's life is only 5 weeks, which means that the adult cicada sings in the summer for a very short time. I haven't seen the light of day for 4 years, and it's only been 5 weeks to sing in the world, so it's not surprising that it always has to be sung enough, and sometimes it makes you upset. 8. Firefly often has to use a crawler - in order to make up for the lack of strength in its own legs and feet - to climb to the top of the bottle, first carefully observe the movement of the snail, and then, make a judgment and choice, looking for a place where it can be hooked.

Then, just a quick and light bite is enough to make the opponent unconscious. It all happened in an instant. So, without further delay, Hotaru began to hurry up and make her delicacy, porridge, to prepare for a few days.

This.. This.. Once the result comes to an end. My heart is always full of moving ......

If the head of an insect is stuffed in the water, the insect will not suffocate to death. The insect's breathing holes are on the sides of the abdomen, not on the head, so if you stuff the insect's head in the water, you won't be able to suffocate it; But if you put all the insect's belly in the water, after a while, it will suffocate and die due to lack of oxygen.

There are many mysteries about insects, and you can take a look at Fabre's book of insects and you will find a different and magical and wonderful insect world. It can be seen by both adults and children.

Fireflies will inject digestive juices into the snail's body to anesthetize and listen to it.

The "mouth" of insects is called mouthparts, and there are several types, such as: stinging, siphoning, chewing, chewing, etc., which are different from humans in many ways.
