Ladybug, meaning "land", belongs to crustaceans, and its homophonic meaning is rich in the world. At the same time, it has gorgeous patterns, taking into account the desire to make great achievements.
Ladybug septempunctata must go through four different developmental stages: egg, larva, pupa and adult. The developmental duration of each stage is mainly influenced by food and temperature. Ladybug septempunctata is a migratory insect, and the foraging behavior of adults and larvae belongs to the transformation of wide-area search and regional centralized search.
Ladybug septempunctata mainly feeds on aphids, sometimes small soil particles, fungal spores and some small insects, and often feeds on plant pollen in autumn. Widely distributed in Africa, Europe and Asia.
The name of ladybird comes from seven black spots on its coleoptera, but the number of spots on its body is different.
Ladybug septempunctata has different activity places in different seasons. In winter, ladybugs overwinter between wheat and rape roots, and some overwinter in sunny clods and soil cracks. In spring, once the temperature rises above 10℃, the overwintering ladybug wakes up and begins to move, which can be seen in wheat and rape plants.
In summer, with the increase of temperature and food, ladybug septempunctata proliferates. All plants parasitized by aphids and scale insects, such as cotton, willow, locust tree, elm, beans and other plants, can find ladybugs, and sometimes even gather in large numbers.
In autumn, the number of ladybugs in the field decreases, and they often lay eggs on corn, radish and cabbage. At this time, the temperature is low in the morning and evening, and ladybugs are often hidden and difficult to be found. They need to be collected after 7 am and before sunset.
