Hey Patd904 Dont listen to a word getagrip had to say because they seriously need to "get a grip" In America it is a Japanese Beetles are aserious pest to rose bushes, grapes, canna, crape myrtles, and many other plants. Japanese beetle adults are aapproximately 3/8 inches in length. The front of the beetle is dark metallic green. Its wing covers are a metalic dark tan. No they do not bite humans so in that respect you have nothing to worry about but left unchecked they will decimate your plants, grass, trees, and vegetables.
Both as adults and as grubs (the larval stage), Japanese beetles are destructive plant pests. Adults feed on the foliage and fruits of several hundred species of fruit trees, ornamental trees, shrubs, vines, and field and vegetable crops. Adults leave behind skeletonized leaves and large, irregular holes in leaves. The grubs develop in the soil, feeding on the roots of various plants and grasses and often destroying turf in lawns, parks, golf courses, and pastures.
Today, the Japanese beetle is the most widespread turf-grass pest in the United States. Efforts to control the larval and adult stages are estimated to cost more than $460 million a year. Losses attributable to the larval stage alone have been estimated at $234 million per year--$78 million for control costs and an additional $156 million for replacement of damaged turf.
So if as you said your tree is loaded with them right now. I imagine by now you've noticed that most if not all your leaves have been eaten and your tree is most likely not doing well. Ask your local home depot or hardware store for the necessary chemicals and how to apply to treat your infestation as they are quite hard to get rid of and seem to be getting worse every year. And getagrip. Why don't you try reading a litte closer what the person is asking as your talking about a LADYBUG!!! This topic is about JAPANESE BEETLES. Hopefully the person did not listen to your ridiculous advice as I'm sure they watched their tree being literally stripped of all its leaves by the beatle voracious appetite and went elsewhere to get better advice.
