Why are there so many ladybugs in autumn.

Because of the dry climate in autumn and winter, the temperature is relatively low in the morning and evening. Now suitable for the Seven-Star Ladybug.

1. First of all, the seven-star ladybug has different activity places in different seasons. In winter, the seven-star ladybug overwinters among the rhizomes of wheat and rape, and some spend the winter in sunny clods and soil crevices. In spring, once the temperature rises above 10, the overwintering ladybug wakes up and becomes active, finding it on wheat and rape plants.

2. In autumn, the number of seven-star ladybugs in the field decreases, it often lays eggs in corn, radish and cabbage, etc., at this time, the temperature is lower in the morning and evening, and the seven-star ladybug is often hidden, not easy to find, and needs to be collected after 7 o'clock in the morning to before the sun goes down. Plus some natural disasters.

The weather phenomenon is serious, and its natural enemies are also increasing, and the temperature is high, resulting in tooth insects and scale insects on the trees.

A large increase, as the natural enemy of these pests, "Sister Hua" naturally soared with the increase in food.

3. From the perspective of ecological and environmental protection, because ladybugs fly from the field to a warmer place every autumn to prepare for hibernation, warm places have become the first choice for them to gather. Although "Big Sister Flowers" bring some trouble to people's lives, they are friends of humans and should be treated with kindness. Be friends with them and don't hurt them.

Because of the drought in the fall, ladybugs are overflowing.

In summer, because the wheat in the field is harvested, there are many ladybugs in the wheat field, and it will drift with the wind and will float to your home.

It's normal for seven-star ladybugs to appear in your home in the summer. Because a certain period of time in summer is the time when the seven-star ladybug breeds in large numbers. So they flew around for no purpose, and they just happened to fly to your house.

It should be relatively normal for seven-star ladybugs to appear at home in summer, and the activities of insects in summer are more frequent, and it is relatively normal to appear at home.

The seven-star ladybug is a natural enemy of the tooth worm, if there is a tooth worm nearby, there must be a seven-star ladybug, and now the winter wheat has a toothworm so the seven-star ladybug will come to eat it.

Because the seven-star ladybug likes your home, it flies to your house in the summer.

It eats aphids, probably planted vegetable crops, so it flies in.

Because of the humidity, or there may be disasters, maybe it will be divided into years.

The seven-star ladybug is mostly due to the overabundance of local aphids, so that the seven-star ladybug has enough food, resulting in a large number of seven-star ladybugs. In summer, with the increase in temperature and the increase of food, all plants parasitized by aphids and scales, such as cotton, willows, locust trees, elms, beans and other plants, can be found on the seven-star ladybug, and sometimes even a large number of seven-star ladybugs gather.
