Seven-star lady beetles, also known as golden turtles, new wives and flower eldest sisters, are predatory insects of the genus Coccinellidae, which are widely distributed throughout China, and are distributed in Northeast, North, Central, Northwest, East and Southwest China. Life has to go through four different stages of development of eggs, larvae, pupae and adults. Let's take a look at what seven-star ladybugs eat.

What food does the seven-star ladybug eat?

Seven-star lady beetle is a kind of beneficial insect, which can prey on wheat aphid, cotton aphid, locust aphid, peach aphid, shell insect, tick lice and other pests, and can greatly reduce the damage of trees, melons and fruits and all kinds of crops to pests. It is called "live pesticide". It is non-toxic and harmless to human, animal and natural enemy animals, has no residue and does not pollute the environment.

Living habits of Coccinella septempunctata

1. Winter: seven-star lady beetles winter between the roots of wheat and rape, and some winter in sunny clods and seams.

Spring: once the temperature rises above 10 ℃ in spring, the overwintering seven-star lady beetle wakes up and begins to move, which can be found on wheat and rape plants.

3. Summer: with the increase of temperature and food, seven-star lady beetles multiply in large numbers. They can be found on all plants parasitized by aphids and scale insects, such as cotton, willow, locust, elm, beans and so on. Sometimes there are even a large number of seven-star lady beetles gathering.

4. Autumn: the number of Coccinella septempunctata in the field decreases and often lays eggs in corn, radish and cabbage. When the temperature is lower in the morning and evening, the ladybug is often hidden and is not easy to find. It should be collected after 7 o'clock in the morning and before sunset.

The interesting phenomenon of seven-star ladybug

1. Catch a seven-star ladybug and gently pinch it with your finger, and your finger will immediately touch some yellow water. this is its protective liquid. It smells bad, but it is harmless to the human body. When the seven-star ladybug is attacked by the enemy, it immediately secretes this foul-smelling yellow water, which scares the enemy and flees in a hurry.

2. The seven-star lady beetle also has the ability to camouflage. When it meets a strong enemy and feels dangerous, it immediately falls from the ground from the tree, shrinks its three pairs of thin feet, like a "loss of consciousness" and lies down dead to hide from the enemy. According to the false death habits of seven-star ladybugs, you suddenly shake the branches of animals and plants, and there are often seven-star ladybugs pretending to be dead on the ground.

3. The seven-star lady beetle that has just drilled out of the pupa shell stays motionless in the pupa shell. At this time, we can do an interesting experiment by suddenly pushing it off with our fingers and bluffing. After more than a day, the seven-star lady beetle's sheath gradually hardens, but the seven spots never appear and become a seven-star lady beetle without spots.
