It should be LEPIDOPTERA pests, and most kinds of larvae harm various cultivated plants. The bigger ones often eat all the leaves or branches. Smaller people often roll leaves, decorate leaves, knot sheaths, weave nets or drill into plant tissues to feed. Adults mostly use nectar as supplementary nutrition, or the mouthparts degenerate and no longer feed, which generally does not cause direct harm. In the classification system, LEPIDOPTERA is generally divided into HOMOPTERA, Heteroptera and HYMENOPTERA according to the characteristics of winged vein sequence, linkage mode and antenna type. Some scholars (O.W.Richards B.R.G. Davies, 1977) claim that it can be divided into five suborders: Lepidoptera, Batmoth, Trichogramma, Single-pore and Double-pore. As for the establishment of ordinary families and families, opinions are not very consistent. For example, some people advocate dividing it into 28 ordinary families and 158 families, while others advocate dividing it into 20 ordinary families and 135 families.
