I remember seeing some really big worms when I lived in the Midwest, that would munch on an entire tomato plant if you didn't remove them. I have not seen any of those so far in the Pacific Northwest. There are other things that make tomato growing hard around here though.

There is always a bit of a compromise when you love both tomatoes and the worms that change into butterflies.

UV rays are really tough on people too. My friend just had a skin cancer removed yesterday.
