For moths that resemble both butterflies and butterflies, apart from silkworm moths that spit silk and can be woven, they are basically terrifying and abominable caterpillars.

The abomination of caterpillars is not only that they are not good-looking, but also that the hairs on their bodies are poisonous and stinging.
For example, this insect with the scientific name of the dancing poison moth occurs only once a year.
And most of the year, they spend most of the year waiting inside the eggs for the right ambient temperature. The waiting period for such diapause can be up to nine months.
However, once the ambient temperature is right, they will break out of the egg.
Due to the miscellaneous food and large amount of food, it will soon be able to eat the leaves in the mountains completely, as if the whole mountain forest has reached the winter of depression again, and a leaf is seen on the bare trunk.
The larvae of the dancing moth stop moving when the temperature is below 10 °C.
Basically do not eat below 15 ° C, only when the ambient temperature reaches more than 25 ° C, it grows faster.
Their male larvae are generally 5 years old, while female larvae are 6 years old.
When these larvae are 1-2 years old, they can spit out like spiders and then switch from one place to another like a swing to live with the help of wind.
This is also such a characteristic, so they are called swing caterpillars.
After several generations of pupae into dancing poison moths, swing caterpillars are not only not as beautiful as butterflies, but they are also very frightening pests.
On average, each poison moth can lay seven hundred and fifty eggs densely, and some can even lay a thousand eggs.
After all these eggs have been broken out of the shell by the larvae, you can imagine how much harm it will be.
It is precisely for this reason that in order to eliminate the harm of the dancing poison moth, the most common use is to manually collect the eggs laid by the dancing poison moth, and then destroy it centrally.
