Tobacco hornworm-these very large caterpillars will decimate the foliage of a tomato plant overnight! The tomato hornworm is nearly identical except that it has a black tail. The adult is a large moth.
Several methods of control-
1. The Texas two step-pick and squash!
2. Bt-Bacillus thuringiensis organic powder or spray.
3. Try feeding them to your chickens-my bantams were afraid of these monsters!
