I have a Hibiscus. I live in Vero Beach, FL. I am accustomed to bugs that eat new growth and cause flower drop, etc. This is unusual because all of the growth on the lower parts of the branches is affected. I guess it has been eaten, though I cannot find evidence. I have treated with assorted sprays and systemics. I have looked at it after dark, thinking it was something that came out then. The flower buds and top growth are fine. There are no deer here. I have inspected very closely and see no evidence of any pests. Can you help me?
