Elaine, I never see them either, but my friend less than a quarter mile away has a gazillion. She also has WAY less spiky and mean plants than I do....she has lots of plumbago, plumeria, various herbaceous perennials, lilies, etc. I have mostly cactus, bromeliads, succulents....but I'm worried about the butterfly garden coming under seige. It's RIGHT by the salt water so maybe that will save me.
