In addition to the cold winter, usually we in the field, woods and grasses, their own flower beds and other places, often see all kinds of ladybugs active, commonly known as "flower sister". Some of them are monochromatic, some have spots on their bodies, some are covered with patterns... It's as colorful as the pebbles of the riverbed.
Many friends, probably because they have read some fairy tales since childhood, have always had the impression of ladybirds, always being plant guards and small experts in catching pests. So I was happy and adopted a warm welcome and protective attitude towards them all. But over time, although the number of pests did decrease, the flowers and plants or crops were also seriously damaged. Why?
It turns out that these ladybugs are not all beneficial insects, and they are also mixed with a lot of "treacherous spies", instead of helping to catch insects, they are the murderers of plants. So which of them are friendly and which are enemies of our plants? Below, the little bee of the weed will come to you in detail:

After reading the above analysis, friends can roughly distinguish the properties of some common ladybugs, right? If in a garden or in a farmland, we encounter an army of one or more types of ladybirds, we should not rush to welcome them, but should first wait and see whether they are enemies or friends, and then make a decision to protect or exorcise them. Even if the number of ladybirds is small, as a small scientific experiment, it is very interesting to identify and observe them occasionally!
