Insect classification:
1, COLEOPTERA: the largest order of Insecta, commonly known as "beetle". There are more than 330,000 species, the front wing is keratinized and hard without wings, so it is called "COLEOPTERA", hence the name. The exoskeleton is developed and the body is hard, which can protect the internal organs. Body shape changes greatly. This kind of insect is very adaptable.
2. Lepidoptera: It is named for its large number of scales on its body and wings.
3. Diptera: Diptera is divided into three suborders: long horn, short horn and ring crack.
4. Hymenoptera: Hymenoptera includes all kinds of ants and bees. Hymenoptera insects have obvious characteristics, including chewing mouthparts, and the connection between the front and rear wings is completed by wing hooks.
