What is this eating the hibiscus leaves? I saw a few caterpillars on the underside of the leaves and by the end of the same day there were six to ten on the back of each leaf. I also saw white "winged" bugs that I did not get a picture of. They were not whiteflies. They were much bigger. The caterpillars were about an inch long and the white bugs were 1/2" to 3/4" long. In this picture, you can see off to the right a small bit of white. Perhaps it is a shriveled up shell from the white bug???? I dusted the plant with Seven and the next day ALL the caterpillars and bugs were gone. I would like to know what they were for future care of the plant.
