Yesterday I found these "chewed marks" on my Van Burren. I know that crotons can get "the new scale", white flies and thrips. These are sucking insects. It was my impression that chewing insects avoid crotons. Looking at the chew patterns, I would guess this was done by a snail. Has anyone had a situation with snails dining on their crotons. Not any other leaf on the plant or the adjacent crotons had any "chew marks". Seems kind of bizarre?
