This bug is all over my Hardy Hibiscus. They all are just crawling with them.....UCK!! The 'Blue River II' is still blooming fine, but my 'MIghty Big Pink' only got three flowers and all the buds are still so small....plus some of the stems are wilting on the top and just curling up.... very hot weather here in West Chester, PA....unusually hot and very dry this year. What are these things and are they harming my plants?
