Yesterday I saw something that I have never seen before in my life. Huge,
green caterpillars on my tomato plants! I never thought I'd spot the biggest
bugs of my life in Colorado!
My attention was first drawn to the plants when I noticed tiny droppings
around the base of the containers (20" pots). Some areas of the plants
looked like the leaves and stems had been nibbled. I finally noticed
several, huge green caterpillars clinging to the stems. They were so well
camouflaged that I have to be about 6" away to notice them.
Here are some close-ups of the buggers:

Anyway, my questions a
1. What are these things? Where did they come from? I planted the tomatoes
in pots with store-bought potting mix. Did they arrive by air?
2. I pried 7 of the buggers off my plants, but couldn't find any more. What
can I do to to prevent them from coming back?
3. Are they poisonous, given that they are eating poisonous tomato plants?
Will birds or other predators go after them?
