This is probably the same critter that targeted bougainvillea last year. Its a caterpillar that can roll itself up in a leaf avoiding most pest control products. Use a product that contains the bacteria called Bacillus thuringensis (Bt - pronounced Bee Tee). When the caterpillar eats a leaf thats been sprayed it will die.
