Scarabs aeruginosa, also known as green scarabs and green scarabs, belong to Coleoptera Scarabsidae, and their larvae are also called grubs. Scarabaeida aeruginosa belongs to COLEOPTERA, Scarabaeidae. The chest back plate and needle wing are copper green and shiny, with fine points engraved on them. The compound eye is red and the antenna is yellow-brown. The soles of the feet and leg joints are yellow. Slightly winged with 4 longitudinal veins on each side. The tibial joint segment of the forefoot has two external teeth. The head of the 3rd instar larva is yellow-brown, and there are two rows of yellow-brown long bristles in the middle of the abdominal hair area on the back of the dirty abdomen, and the tips of the bristles mostly intersect.

The larvae overwinter in the soil and are unearthed after the soil thaws in the following spring. The peak of adults is in mid-June, but it lasts for nearly 3 months. After peeling twice, the hatched larvae grow into 3rd instar in September, that is, 3rd instar larvae hibernate at a depth of about 6 inches below the topsoil. Adults lurk in the topsoil during the day and start to move at sunset in the evening. The damage period is long, the migration is strong, the appetite is large, and the eating habits are miscellaneous. The main hosts are: apples, grapes, pears, peaches, plums, walnuts, hawthorn and other tree species, among which apples suffer the most. Scarabs gather in groups on trees to feed on leaves, and damaged leaves are incomplete. In severe cases, only the petiole is left, and even the leaves are eaten up. Larvae feed on fruit tree roots, which seriously affects the growth and yield of young trees and causes great economic losses.

Mainly distributed in Heilongjiang, Zhejiang, Jiangxi, Jilin, Liaoning, Hebei, Inner Mongolia, Guangxi, Guizhou, Shanxi, Shandong, Henan, Hubei, Hunan, Anhui, Jiangsu, Sichuan, Ningxia, Shaanxi and Guangdong. Mainly distributed in warm and humid areas with abundant rainfall.
