You are most welcome Alex.
I must say however that not all insects are limited to eating a single part of a plant. Manduca quinquimaculata the tomato hornworm (A Hawk moth caterpillar) can devour an entire tomato plant overnight leaving nothing but a stumpy stem.

They dine on strap leaf plants, bulbs and flowers. They range in size from about 2.25 inches to about 4 inches and can destroy amaryllis, crinum lily, daylily, etc. but will eat pretty much what ever they come across as they are not terribly selective. They are considered plant eaters, but research has shown that they are also opportunistic carnivores.
