Um. Okay... Who did this? I don't think the grasshoppers would take big chunks like this. They actually prefer to chew up my roses. I feel like this could be the work of a caterpillar. The question is, what kind? I looked both Angel Trumpet trees over (They're in pots so they're not that big), and I didn't see the culprit. Apparently Brugmansia tastes as good as it smells if you're an insect!
