Hookworms on my Tomato plants

The bright green, rather hansom, caterpillar ate. I waited. He ate. I wondered, maybe he's a beautiful butterfly getting ready to hide away for the big metamorphosis. He ate. And I resorted to research. He's destined to eat the whole plant and then become a moth. Not that I have anything against moths, but I'm not as willing to sacrifice my tomato plant for them. Removal was the answer. Tomato plant saved for future humans not future moths.
