草坪变黄，还有好多小虫子，是生病了吗？

邻居家铺了新草坪，刚开始绿油油的，突然有一天发现一下子变黄了，我家的和邻居家比较接近的草坪也开始变黄，邻居家对门那家临街的草坪也开始了，有蔓延的趋势。

而且在变黄的草坪附近有好多这种红头的小飞虫，不知道是不是这种虫子搞的

没见过这种虫子，进来看看是否有人认识这种虫子

我查到了，好像是这个东西
Spider/Parasitic Wasp (family Pompilidae)
If there are orange/red and blue/black wasps flying over your lawn, this will usually indicate that there are grubs present, as the wasp is looking for a host to lay its eggs. So, it’s not so much the wasp that is the problem, as it will be a sign that there is lawn grubs feeding off the roots of your lawn. The great thing about these wasps is that the adults do not sting and because their larvae is a parasite of the grubs, they actually help to control the grubs.

就是说有lawn grubs了，不知道我的理解对不对
