Today observation

The life of the silkworm begins with the small ant silkworm drilled from the egg, and then becomes a small silkworm after several times of molting, and then spins it to turn it into a silkworm cocoon formed by silk, and then drills it from the silkworm cocoon. When it came out, it became a moth and then died.

When the small ant silkworm is drilled out of the egg, it is only as big as an ant, black and small. It swings its thin body and seems to ask: "Where is the mulberry leaf?" If you cut the mulberry leaves into strips, On the back of the small ant silkworm, the small ant silkworm will immediately climb up to eat the mulberry leaves. During the small wormworm period, you should let them eat and eat well. The mulberry leaves should be fresh and dry, and cut into pieces or strips to facilitate the ants to eat. It is also necessary to remove the feces of the small ant silkworms and the leftover mulberry leaves to keep the "rooms" of the small ants silkworms clean.

When the small ant silkworm turns into a small silkworm, you will find that there are small black spots on both sides of the silkworm body. The small black spot is the "valve" of the silkworm. The small silkworm uses it to breathe fresh air, when the small silkworm is slow. When you grow up slowly, you can clearly see that the silkworm will swing up and down when eating the mulberry leaves. Sometimes you can see it with the three pairs of feet on the head to hold the greedy eating of the mulberry leaves.

When the small silkworm is about to become a cockroach, it will not eat anything like a sick child for a few days, and will stay quietly at the corner of the box. Don't worry about this time, it is because it has to be silky. The silk that it spits out will turn it tightly inside and turn into a cockroach. Perhaps what people say is “doing self-binding” is this stage of it!

The last stage is the "moth". The silkworm in the scorpion eventually became a "moth". Perhaps it was not willing that the thick silk wrapped itself. It bit the broken cocoon and came out. After it came out, it would fan its wings and beat it hard. dry. When the moth and the other moth are opposite to the tail, it means that they are mating, don't pull them apart, or the moth will die. When the moths are finished, they will leave a lot of small black spots, that is, silkworms. The eggs will turn into a cute little silkworm in the spring of the following year, beginning their ordinary and glorious life.
