Hummingbird moth, also known as hummingbird butterfly moth and hummingbird moth, literally translates into English as hummingbird hawk moth. Hummingbird moth was like a butterfly at first, with a long beak tube and swollen tentacles at the top; It is like a bee, which can make a clear and audible buzz; It is also like a hummingbird in South America. It doesn't sleep at night, comes out during the day and seldom rests. Like a hummingbird, it sometimes rushes among flowers and sometimes hovers in front of them when it is looking for food. But in fact, it is a kind of moth and a close relative of butterfly. Hummingbird moth has many unique habits and characteristics: unlike butterflies, it has a thick abdomen, fast flight speed, cocoon habit and adult overwintering; Unlike bees, flowers don't carry powder, honey doesn't make honey, and they can be hung in place to feed; Unlike a bird, it can move back and forth when circling. Because of its unique physiological characteristics, it is rare in northern China. Hummingbird moth is called the "four unlike" in the insect world. First of all, it moves in the daytime like a butterfly, with a long beak and enlarged tentacles at the top; It is also like a HYMENOPTERA bee, dancing among flowers in summer and autumn, feeding on nectar and making a clear and audible buzz; It is also like a hummingbird in South America. It doesn't sleep at night, comes out during the day and seldom rests. Like a hummingbird, it sometimes rushes among flowers and sometimes hovers in front of them when it is looking for food. ? In recent years, it is reported that hummingbirds have been found in many places in China. Hummingbirds are endemic to South America and have no distribution in Asia and China. Hummingbirds are actually mistaken for hummingbirds and moths. In animal classification, the basic feature of hummingbird moth is actually a kind of moth in the insect world, and it is a close relative of butterfly, but it belongs to the suborder Moth. Hummingbird moth has many unique habits and characteristics: unlike butterflies, it has a thick abdomen, fast flight speed, cocoon habit and adult overwintering; Unlike bees, flowers don't have powder, honey doesn't make honey, and they can be hung in place to feed; Unlike birds, they can fly back and forth when circling, and so on. This insect is very similar to the hummingbird in terms of weight, appearance, living habits, flight speed, etc., except that it has a pair of antennae and no feathers on its wings, so it is named hummingbird moth by biologists. Because it is too similar to hummingbirds, it is difficult for many experts to distinguish between true and false in flight. There are also reports at home and abroad that hummingbird moths are mistaken for hummingbirds. Two hummingbirds photographed in hengjiang town, Yibin County are similar in length and size to a wasp, mainly yellow with black and green patterns in the middle. According to experts, this hummingbird moth is a rare insect produced in the United States, which was rarely seen in China before. Now it is reported in newspapers and media, which is probably related to imported flowers.
