form

Egg: milky white, round, with a diameter of 1.2 ~ 1.4 mm, which will turn milky yellow when hatching. Larvae: The newly hatched larvae are milky white with a light brown head. The body length is about 0.8 ~ 1 mm, and the larvae crawl around the eggshell for 3 ~ 5 minutes, then climb onto the eggshell and eat the eggshell slowly with their mouths to supplement nutrition. After feeding, the larvae turn pale green, which is consistent with the color of leaves. It's hard to find if you don't pay attention. Mature larvae are white-gray with large black spots on their backs. Pupa: The pupa is 42 ~ 46 mm long and 9 ~ 10 mm wide. The stiff pupa is light yellow brown, and it is dark black brown when it is near emergence. Spread your wings 55 ~ 6 1 mm wide. The upper wing is brown, and the color is lighter near the outer edge; There are two distinct orange-red tufts on the back of the back chest. There is not much difference between men and women. Similar species are castor bean and castor bean.

White-shouldered moth is one of the main pests of hydrangea, which damages the leaves with larvae, resulting in the failure of hydrangea to grow and bloom normally, and even the death of the whole plant in serious cases. Host plants include hydrangea, Changshan, grape and impatiens.
