I have strong negative feelings about Japanese beetles. They swarm in as my Nevada rose comes into bloom and about 20 of them munch down on the fresh flowers destroying it within minutes. Same with some of the Clematis flowers. I always seem too busy to go and make some safe soap to sprinkle on the plants.
I was in the garden the other day during that heat wave and discovered about 20 of these moths- Ctenucha Virginica on the flowering Goosneck Loosestrife . I think they are so elegantly clad. Looks like Dior got a hold of them! Sure beats the ugly Japanese beetles in their hard war- like armor!
