Many different types of ladybugs to eat the harmful plants, such as potato beetle; also beneficial predator insect ladybug, if the main predator of citrus red ladybug pests. Ladybug's head is very small, often hidden in the first part of the pronotum below. Students have a pair of large compound eyes and a pair of antennae, like the same stick. It is now commonly used to combat damage crops ladybug aphids. Coccinella septempunctata, Harmonia axyridis red ladybugs and aphids and scale insects are prey for beneficial insects. Ladybug is probably the most famous garden is the most popular residents, because they are charming and well-behaved, color Banlan, but they are also a predator, but is a more voracious predator.

Hunting adult
Adult ladybirds prey on insects of any meat soft and tender, their most like to eat aphids, but as long as there is no put on armor and other protective coat, and body flexibility, small size of insects, are likely to be their meal. Prey are not the right time, ladybug must often flew to the search target. Ladybug looks unlikely to fly, its body is not like a pilot, but more like a medicine cabinet. It has a hard coat, and its small and delicate _set_ of wings out from under the jacket, crazy dancing. Ladybug is indeed a skilled aviator, it is precisely because of their superb flying skills, so can every corner of the garden come and go freely. Female ladybug will produce large quantities of eggs, it is usually distributed in the eggs where aphids often come and go in order to ensure their children after birth to maximize the probability of survival. Eggs are hatched, the new-born larvae will be put around the aphids as they are delicious snacks, the appearance of the larvae is very different from its parents, they are not equipped with a thick armor, the body is very soft, like distribution into a section , but with some hard, long mane, can play a protective role. Their sturdy jaw, the shape is like a pair of pliers, can easily penetrate the aphid's body.

Larval life
Monotonous life of the larvae, they stayed in the flowers every day between the crazy prey aphids, ladybugs eat more than than the adult. Ladybug's Life is very short, the growth from egg to adult takes about one month period of time only, so no matter what, we can also found in the garden ladybug eggs, larvae and adults. Over time, the ladybug larvae growing appetite, the body is continually growing, they must break the shackles of the old skin, and began an arduous journey - molting. This process is not as we took off old clothes, and back to a large coat that simple. Ladybug lifetime to undergo molt 5 to 6 times each molt, the body will continue to grow until sufficient energy savings into the pupa stage. When the ladybug ready to pupate, it will first find a safe place to hang their leaves attached, and then began to experience a breathtaking transformation. It passes from one body into a strong physique delicate larvae to adult ladybug. This is a mind-boggling process, the larva's body will be broken down, and then reassemble, adjust, coupled with a modified dress, all this in order to meet its new life. When it finally broke into a pupa, a new one out when the adult ladybug, but also experienced some changes, because at this time it's body is still soft and delicate, not yet fully mature, it must be exposed to the sun, absorb oxygen, it's body color slowly deepened, markings will gradually reveal themselves a few hours later, it will become, and the garden exactly the other adult ladybug.

Ladybug's residence
瓢虫的居住
And all the wild animals, like humans do not ladybugs have a house to shelter. They can only be strong to endure all kinds of inclement weather, and sometimes they will hide in the leaves under the umbrella as shelter from the storm. For insects, a raindrop has many meanings. If they want water, then the rain is equivalent to the pool, one can not see the end of the huge glass. Of course, for aphids, the rain even more the Titanic. The surface tension of water droplets can also be made into a swamp as small as insects, can not extricate themselves.

About Coccinella septempunctata
Commonly known as Hua Dajie. Distributed in northeast China, north, central, northwest, east and southwest and some other provinces; also recorded in Mongolia, Korea, Japan, the former Soviet Union, India and Europe. Adult body length 5.2-6.5 mm, width 4-5.6 mm. Ovoid body, back arched, was like half a bailer. Head black, compound eyes black, yellow inside indentation have a point. Antennae brown. Mouthparts black. On the additional side is yellow. Pronotum black, the former have a larger top corner past a square yellow ground. Scutellum black. Elytra red or orange, a total of seven spots on both sides; wing base in the scutellum on each side of a triangle Geotrichum. Abdominal and foot black body. Occurred in multiple generations. To adults over the winter, the following year 4 moonrise hibernation. Eggs in a host aphids on plants. Adults and larvae are a variety of aphids, fleas, etc. for food. Department of beneficial insects and should be protected. Coccinella is a famous natural enemies of pests, the adult can prey aphids, Aphis gossypii, Huai aphid, green peach aphid, scale insects, ticks and other pests, can significantly reduce the trees, fruits and a variety of crops suffer pest damage, been referred to as "living pesticides." Coccinella septempunctata Coleoptera Coccinellidae is a predatory insect, widely distributed in all over the country. 70 20th century, the Yellow River has started to move with the help of controlling cotton and wheat aphid, 90 years of artificial breeding and production. Coccinella septempunctata Coleoptera there are seven black spots on the name. Several generations occur each year varies from region to region. For example, Anyang in Henan 6-8 on behalf of each year. Northern cold regions, a smaller number of generations each year. Coccinella septempunctata, long life, an average of 77 days, to adults and larvae prey aphids, spider mites, whitefly, corn borer, Helicoverpa armigera larvae and eggs, etc.. Coccinella septempunctata a female can lay 567-4475 tablets, 78.4 eggs per day, up to 197. Food consumption of Coccinella temperature and prey size and density. Feed on aphids, for example, in the low prey density, prey density increased with rising exponentially; in the higher density, the predator showed a level close to the limit. High temperature conditions, the impact of the activities of Coccinella septempunctata and the ability of prey, predation rates. According to statistics, on the tobacco aphid Coccinella average daily feeding amount: 1 age 10.7, age 33.7 2 3 age 60.5, age 4, 124.5, adult 130.8. Coccinella 80 days of life may be feeding thousands of aphids. Coccinella septempunctata toxicity to human, animal and animal predators nontoxic, no residue, does not pollute the environment. Coccinella is fairly well distributed in China, the distribution areas of Beijing, Liaoning, Jilin, Heilongjiang, Hebei, Shandong, Shanxi, Henan, Shaanxi, Jiangsu, Zhejiang, Shanghai, Hubei, Hunan, Jiangxi, Fujian, Guangdong, Sichuan, Yunnan , Xinjiang, Tibet, Inner Mongolia and other places, common in farmland, forests, gardens, orchards, etc.. Coccinella is a famous natural enemies of pests, the adult can prey aphids, Aphis gossypii, Huai aphid, green peach aphid, scale insects, ticks and other pests, can significantly reduce the trees, fruits and a variety of crops suffer pest damage, been referred to as "living pesticides." Coccinella septempunctata have a stronger self-defense capability, although the body is only so much soy, but many powerful enemies are helpless to it. It is three pairs of small joints of the foot, there is a "chemical weapon", when faced with the invasion of predators, it's the foot joints can secrete an extremely smelly yellow liquid, so that the enemy can not stand the panic retreat or escape. It also has a play dead ability, when faced with enemies and danger, it immediately fell to ground from the trees, the three pairs of small feet under the contraction in the stomach, lie down and play dead, hide from the enemy and survive. There is also a wonderful ladybug habits between: clear boundaries between beneficial insects and pests, without disturbing each other, and do not intermarry, maintained their traditional practices, so no matter how many generations passed down, will not have a "hybrid", it will not change their traditional habits.

Ladybug's life cycle takes about four weeks, it can breed several generations each summer. Soft, slender larvae, usually gray, with blue, green, red or black spots, to other insects or eggs for food.
