Something's eating my bougainvillea

turns out the guy at rosette's tells me that it was probably too much water from all the rains. He says too much and too little can have same effect. Advice is that if you're getting a lot of rain, pull back your mulch; too little rain, cover the base of the plant. They're looking MUCH better with more balanced rain now. But will continue with the regular systemic insecticide treatment. Thanks, everyone.
