Caught him red handed.

I wasn't able to get a picture, but I caught the bugger eating my plants.  It was a cabbage worm.  The little critter was green and blended in.  I almost didn't see him.  Anyway, it was about an inch long and fuzzy.  I should do some more research to see what can be done about them.  It's probably too late.  Most of my cabbage plants are too far gone.
