I grew up in a city built on wetlands. The ecology there is very good, with reeds that can't be seen at a glance. Insect netting is a must-have toy for boys, I like to endure a mosquito bag to catch butterflies and dragonflies, and I also like to catch vegetable insects and put them in the mouth of the ant hole to watch the ants torture the vegetable insects.
Before the teacher in the nature class encouraged me to raise a vegetable worm into a vegetable butterfly, I never thought they were the same thing. It's a bit of a pity that I didn't observe the process of turning butterflies into butterflies. Later, many times I did not observe how they were drilled out of the pupae. After all, the process of transforming butterflies may only take half an hour, and there is no way to always stare at the glass bottle.
Childhood regrets always leave a lifelong obsession. I had a caterpillar in my flesh the year before, and when I caught the bug, I almost had the idea of raising the bug. So even though the worm ate a lot of my flesh, I was kind enough to throw it on the first floor to eat tomatoes.
The pest area is a terrace on the 2nd floor, facing west and half facing south, with direct sunlight from 2 o'clock in the afternoon. Below the terrace is a small courtyard on the first floor, and the owner of the small courtyard has grown many tomatoes, cucumbers and bitter melons.
It was already the beginning of July, and Tianjin had entered the heat. All the flesh was in a relatively weak state, and only a large pot of thunder children was still blooming madly against the sun. I saw a petite little blue-gray butterfly dancing around the flowers. Although I also know that butterflies may come here with bad intentions, it is somewhat careless because they have never suffered from this type of insect infestation before.
About a week or so later, when I was watering in the evening, suddenly one of my large pots of tower pines disappeared, and the pot of tower pines looked like 20 trees. Because it was late, I thought who had helped me move my position, and I didn't care too much. It wasn't until the afternoon of the next day that I was surprised to find that the pot of ta pine was in its original place, except that all the ta pine had withered, the color had turned gray-blue, and the bitten leaves were scattered in the pot. Since all the tower pines were hung up without falling, I only thought it was an empty pot last night and ignored it.
It was then that I realized the ferocity of the butterfly. But after examining all the flesh, I couldn't find the murderer. The only thing that is certain is that the caterpillar has never left, it must be hiding under the leaves of some fleshy tree and chewing on it.
By noon the next day, a bluestone lotus had lost several leaves, and there were traces of insect bites on the pole. I searched carefully in the flesh around me, and finally Caught the culprit in a basin of first love.
It turned out that the caterpillar, after biting the blue stone lotus, climbed into the pot next to the first love, bit a hole near the stem on the back of an old leaf of the first love, and then drilled into it. Because it almost ate the entire leaf, I saw the figure of mao mao on the front of the leaf, which caught it.
To make sure the caterpillar was the larvae of the blue-gray butterfly I saw, I posted the photo to the Baidu Insect Bar. You must not have thought of what kind of answer I got, and the bug friends replied to me: Wow, so cute, this is the baby of the butterfly. I angrily said it ate my whole pot of Tasong. As a result, the insect friends were very happy to ask me what Atasong was, so that the worms loved to eat, and they also wanted to raise some to feed the caterpillars. After reading the reply, I knew that bug friends and flower friends were destined to have no common language.
Things don't end so simply. In that summer, I caught at least 10 caterpillars, at least 30 flesh plants were bitten or mutilated, and at least 1 caterpillar successfully survived and faded into a butterfly (I found the pupa shell left by the feathering of the caterpillar). The caterpillar became the worst disaster I encountered that summer of the year.
The Butterfly only needs to stay on your flesh for 2 seconds to complete the task of spawning eggs. They lay only one egg at a time, then fly away and change into a pot of meat.
Legumes are also a favorite food of the butterfly

The eggs of the butterfly are generally round and round, yellowish-white in color, or white. But because they have to keep the eggs out of the sun and lay on the backs of leaves, on the sides, or on the poles of flesh, we rarely see them at a glance. Although killing the caterpillars before they hatch is the most popular option, unless your meat is only a few pots, the difficulty is comparable to finding a needle in a haystack.
A butterfly is an elegant insect, even its unassuming gray butterfly. They don't eat everything. If you only have cacti, euphorbia or twelve-volume meat on your balcony, you don't have to worry about butterflies, because no domestic butterfly can look at these foods.
Butterflies tend to be quite specific about their parasitic plants. For example, the famous Dali Butterfly Spring can attract thousands of anchovies and butterflies because there are huge acacia trees as host plants. Flower lovers in the north rarely see beautiful butterflies, while in the south it is very common because the north lacks plants such as camphor trees, cloud fragrance, magnolias, and aristolochia that butterflies like. As we all know, silkworms only eat mulberry leaves, and silkworms only eat tulip leaves, and never eat other foods. The adult silkworm moths of these baby silkworms are actually very picky insects like the larvae caterpillars of butterflies.
There are more than 200 species of grey butterflies in China, but fewer than 30 species of grey butterflies are interested in the flesh of the sedum family, which is a more common one. Their favorite food is mainly sedum and the flesh of the genus Apatosaurus, followed by the genus Lithopoe and Varson. If there is a sedum of the family such as Tasong, Himebuki, and Buddha's Beetle grass, the gray butterflies are often the favorite. The favorite meat of this type of gray butterfly is now very cheap, and it can be planted in a large pot to attract gray butterflies to lay eggs, so that gray butterflies are less likely to harass the relatively expensive meat.
The eggs of gray butterflies generally hatch into larvae in about a week. From the 5th to the 10th day after seeing butterflies flying, spraying the flesh with stomach-toxin insecticides is the most effective. Gastric drugs are those drugs that can be toxic when eaten into the stomach. If the caterpillar bites the sprayed leaf, it will be poisoned.
Spraying the insecticide prematurely, the eggs have not yet hatched, and because the eggs have no nutritional exchange with the outside world, the drug will fail because it cannot break through the protective film of the eggs. Spray too late, the caterpillar grows too large, it will cause more serious damage to the meat.
The earliest insect pests generally occur on the flesh of the eggs laid by the gray butterfly. Pay attention to the change in the state of meat and meat to detect insect pests as early as possible. Newly hatched caterpillars prefer to hide behind shady leaves, short stems, and so on. When spraying the drug, the sprayer that has to spray a fine mist spray from the side, just spraying on the surface of the blade is not a problem.
The larval stage of caterpillars is up to one month. When they grow to more than 2 centimeters, their appetite is not as good as when they were young, and they will find a leaf to bite a hole in and eat while recuperating. Some caterpillars can also drill into poles. If not carefully observed, caterpillars at this stage are difficult to spot. Because they hide in the leaves of flesh, spraying is also less lethal to them.
summary:
1. The most fundamental way to prevent the harm of gray butterflies is to focus on prevention. Sealing the terrace with insect nets so that butterflies don't have a chance to fly in is the easiest and most effective way.
2, found butterflies flying than the discovery of insect eggs is much easier, after seeing butterflies 5-10 days, you can spray insecticides with stomach poison effect, let the baby die of the first bite of meat in life is a cruel and effective way.
Why is the second article bolded? Why? There is an answer at the end of the article.
3, gray butterflies are very picky eaters, if there are delicious varieties, they will never retreat to the second. Sedum is an important plant that attracts gray butterflies, so if grey butterflies have to eat them, eat something cheap.
4, fire festival (or red ghost city, autumn leaf festival can also be) is also a favorite food of butterflies, fast growth, strong resistance, you can also plant some to feed butterflies. The good news is that after the fire sacrifice is bitten by a caterpillar, it can also burst out of the side bud from the wound. Can be red, can be beautiful, can attract butterflies, can be bitten and can also burst out of the side buds, fire sacrifice is really a good meat. There are pictures to prove it.
Extension of the bold words in the previous article:
1, I said the best stomach poison drug, non-avermectin, this is the ultimate weapon against biting pests.
2, this is to prevent photolysis of water dispersion granules, there is no problem of powder scattering, very suitable for home use.
3, after 5 days after the butterfly flying spraying is the best, because the hatching of the caterpillar takes time, if the spray is too early, the caterpillar hatching after the efficacy has been weakened. If sprayed too late, the caterpillars will eat too much meat.

Encyclopedia Jun Fragmented Thoughts: The fact that the larvae of the grey butterfly destroy the meat has also been emphasized many times in the encyclopedia, because they destroy very quickly, drilling into the succulent leaves and even the stems, you can eat all the meat in a short period of time, when you find it may be late, so prevention is very important!
