Worm Invasion

My tomato growing skills have been severely challenged by an invasion of big green caterpillars known as tomato or tobacco worms. Our "Worms Squished To Date Count" is up to 36. The record for most worms squished in one day is 21. 

One website identifies the red horned worm as a tobacco worm. The horn end is actually the back end of the worm and the black droppings, the worm's poop, is called "frass."

These guys defoliated the tops of our tomato plants in a few days. They are nasty critters that eventually become a large moth.
