Everyone knows Coleoptera. (Oh, cockroach, you are so...)

This is not a scarab beetle.

Scarabs belong to the family Coleoptera, and the one in the picture is obviously a type of leaf beetle, which belongs to the family Chrysomelidae under the same order.

I really don’t know the specific species. I searched for the corresponding photos and it seems to be the elm green hairy leaf beetle.

Did the outbreak occur among street trees or plantations?

Brother Goose Huang, finally caught you to make mistakes, hehe .

This is definitely not coriander, it must be leaf beetle. It's a bit similar, expressed in body color. But coriander is slightly larger and narrower, and the leaf armor is smaller and rounder.

In addition, you can search for coriander and leaf beetle respectively on Baidu pictures, and you can see them clearly at a glance.

Crysanthemum belongs to the superfamily Chrysomelidae, and Chrysanthemum belongs to the superfamily Chrysomelidae. There is still some distance between the two classifications... although they are not far apart in Coleoptera...
