Flower lovers who like to raise succulents are often very afraid of shell worms. Because mesozoans are difficult to eradicate, they may also cause bituminous coal disease, making our flesh miserable. In fact, dew breeding succulents, do not only prevent shell worms, people and animals harmless beautiful little butterflies are more hateful, they will directly lay eggs on the flesh, eat empty leaves. This small butterfly is the dark gray butterfly, which has now entered a high incidence period, and the prevention and treatment work must be done well.
<h1 class="pgc-h-arrow-right" > what is a butterfly</h1>
The Grey Butterfly is a relatively small butterfly that looks beautiful. When the weather is nice, they will move in large numbers and dance among the flowers. When the butterfly dances among the flowers, more than 90% of the flower friends will feel very beautiful, if it stays on a certain flower, it feels more beautiful, and will hold its breath and appreciate it carefully. In late spring and early autumn, the butterfly is more active, and we can easily see it.
In fact, the harm of the butterfly to the plant is very large, they will lay eggs on the plant, and after the eggs hatch, they will gnaw on the leaves. The leaves of flowers and grasses that have been eaten by the larvae of the butterfly are also prone to black rot. The butterfly especially prefers to lay eggs on succulents, and when it encounters exposed succulents (especially sedum), it will not be missed as long as there is a condition. So, recognize this beautiful little butterfly, don't think that it stays on your flesh is beautiful, staying for a long time is not to say that it is laying eggs.

Nibble on the leaves
After the butterfly lays its eggs on succulents, the larvae hatch and burrow into the leaves and begin to gnaw on the flesh inside. Until one leaf is gnawed into an empty skin, and then another leaf is entered. The larvae of the butterfly nibble on succulent leaves, which are difficult to spot at first because they nibble from the inside and the leaves appear to be intact on the outside. By the time we found out, all that was left was the empty skin. The larvae of the butterfly mainly nibble on succulent young leaves, the middle and upper leaves are easy to hit, and the old leaves below are often fine.
Causes decay of leaves and stems
The larvae gnaw on succulent leaves (and sometimes the stems), and the wounds are prone to decay. Especially on rainy days, the chance of the wound rotting is very high. Some flower lovers see the rotting of succulent leaves and stems, and they think that they have black rot, but in fact, it is not black rot, but the larvae of the grey butterfly are playing ghosts. Therefore, if you don't find that there are grey butterfly larvae on the succulent, the succulent may rot and die of the whole black rot. My wax peony was eaten by the larvae of the grey butterfly last autumn, and several of its heads were blackened and the plant type was completely destroyed.
Attract more grey butterflies to lay eggs
The butterfly found that there is a suitable succulent to lay eggs, and will not "swallow alone", it will leave some secretions, telling other butterflies that this place is very suitable for babies, hurry up. As a result, more and more gray butterflies will come to this succulent to lay eggs, making the succulents look beyond recognition. So, if you find one or two grey butterfly larvae on your succulents, don't think that you will be fine if you catch them, it is likely that there are many eggs on them that have not hatched, and it is not said that they will erupt one day.

1. Frequent inspection
If you find a grey butterfly staying on your succulent or flying around, you should carefully check it to see if there are any eggs on it. The eggs of the grey butterfly are still relatively easy to find, round balls. If you find the eggs, clean them up in time and don't let them fall in the pots. If the exposed breed is succulent, cleaning up the eggs will be very cumbersome.
In addition to checking for the presence of grey butterfly eggs on the succulents, check for any hatched larvae. The larvae first nibble on the back of the leaf, and after nibbling out a window, they burrow into it to eat the leaf flesh. If you find that one of the leaves of your flesh is dry inside, and there are 80% of the worms, uncover the skin of the leaves, and a small fleshy, green insect lies in it, and it can be killed.
2. Spray prevention
If you are worried that the succulent will be plagued by the larvae of the grey butterfly, and if you find that there is a grey butterfly flying, you can spray the whole plant to protect the flower god, and it will not lay eggs on it. Spraying the flower gods is best done in the evening, and the leaves are sprayed both front and back. Especially the succulents that have been stayed by the butterfly should be sprayed carefully.
In addition to spraying the flower god can prevent the larvae of the gray butterfly from nibbling on succulents, you can also use internal insecticides, such as the commonly used small white medicine, buried in the pot, which can also greatly reduce the chance of the outbreak of the butterfly larvae.
Have your succulents ever been plagued by the Grey Butterfly? In addition to succulents, the butterfly also lays eggs on other plants. In short, it is not a good thing to see the gray butterfly wandering around your flowers and grass, you should be vigilant. Now is the high incidence period of egg laying of the grey butterfly, dew-raising succulents are not only anti-shell insects, but also the grey butterflies must also be prevented!
