In late spring and early summer, the sun is bright and not warm, the sky is calm, the grass and trees are happy, just suitable for traveling and enjoying the scenery, but sometimes encountering some "uninvited guests" often make people retreat three feet, and these "uninvited guests" also give maintenance personnel headaches!
Heather leaves are incomplete, "full of sores"?
Boxwood leaves are scorched incompletely, and adult plants die?
Privet leaves only the upper epidermis, forming a "skylight"?

1 generation of annuals in the north, 2 generations in the lower Reaches of the Yangtze River, a few 3 generations, the larval occurrence period is from late May to October, August is the most harmful, common are flat thorn moth, mulberry brown thorn moth, green thorn moth and so on.
【2】Inchworm:

Speaking of the American white moth, the first thing that comes to mind is its ferocious eating phase, often eating miscellaneous, large reproduction, up to hundreds of thousands of larvae on each tree, serious can eat all the leaves of the host plant, and eat the bark, once encountered it can be described as "once back to the pre-liberation". In North China, three generations occur a year, and the larval infestation periods are from early May to late June, mid-July to mid-August, and early September to mid-November.
【4】Chongyang wood brocade moth:
The harm of the Heavy Yang Wood Spotted Moth is a common problem in the garden industry, mainly harming heavy Yang Wood, larvae eating leaves, eating leaves in severe cases, and only leaving leaf veins. The occurrence of algebra varies from region to region, with three generations occurring a year in Zhejiang, and the three generations of larvae are infested in late June, early to mid-July, and mid-to-late September.

The hatching larvae mainly feed on the back of the new shoot leaf, nibble on the flesh of the leaf dorsal leaf, leaving the upper epidermis, and as the leaf damage area continues to expand, the "skylight" phenomenon is formed. When the harm is serious, it can cause the entire privet to wilt and die. The larval infestation period is from mid-March to mid-May.
