What are the three differences between beetles and ladybugs? Do you know?

The first time I met the beetle was when there was a host with the same name in the windmill. Later, I learned that the beetle was originally an insect class. Many people say that beetles are seven-star ladybugs? In fact, they are two kinds of insects, so what is the difference between beetles and ladybugs?

I. different social behaviors

Second, the difference in appearance

The adult body of the beetle is mostly oval or oval, with Gill-shaped antennae, composed of 9-11 segments, each of which can be opened and closed freely. The seven-star ladybug is oval and ladylike. There are seven black spots on both sides of it, which is a very obvious difference between its belly and feet.

Third, the difference of life habits

Most of the beetle larvae feed at a depth of more than 10 centimeters, and generally crawl to the surface from the depths in the early morning and dusk in summer, biting the stems, main roots and lateral roots of bamboo willow near the ground. Adults have different feeding habits, some feed on plant roots, stems and leaves, some feed on decaying organic matter, and some feed on feces. The larvae are mainly in the soil and feed mainly on organic matter in the soil.

Coccinella septempunctata is very common, but it is still a symbol of organic agriculture. It is less likely to cluster. But adults looking for food are often seen in outdoor aphids.
