Willow beetle.

In Fabre's (author)'s writing, the willow beetle is like a miser, wearing a short tuxedo that seems to be "missing fabric", and the little sparrow bitten by a poisonous spider, It will also "eat happily, and even cry like a baby if we are slow to feed it."

His "Insects" was regarded by Lu Xun as a model for "talking about insect life".

Life habits

Beetle larvae eat tree trunks and branches, affecting the growth and development of trees, weakening them, causing the invasion of pathogens, and easily being broken by wind. When the damage is severe, the entire plant dies, the wood is eaten away, and the craftsmanship value is lost. Longhorn beetles are mainly pests of woody plants, eating tree trunks, branches and roots in their larval stage.

Some are harmful to herbaceous plants, with larvae living in stems or roots, such as Chrysanthemum beetle, Melon beetle, etc. Some species, such as Capsella gossypii, are harmful to Capsicum gossypii. There are also a few species whose larvae do not live in plant tissues, but feed on roots in the soil, such as big-toothed and bent-toothed saw beetles, grass beetles, etc.
