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!
