Living habits:

Nymphs begin to hatch in early April. The average duration of the first instar nymph is 265,438+0 days, the second instar is 8 days, the third instar is 65,438+00 days, the fourth instar is 65,438+07 days and the fifth instar is 26 days. After 82 days, they became adults. Newly hatched nymphs gather near the eggshell and begin to disperse after a few hours. Nymphs like to perch on the top of branches, prick and suck on branches of flowers and fruits, and suck the juice of twigs, buds, ears and young fruits. It often leads to serious falling flowers and fruits. In case of wind and rain, run away from the back of leaves, shoot smelly liquid for self-defense when disturbed, or fall immediately, and the nymph falling on the ground will fly back to the tree soon.
