Small caterpillars eating leaves

Hi everyone. It seems that very small caterpillars are eating my leaves. The leaves are infested on the underside with about twenty or more. The leaves end up as nothing but a veiny skeleton. These are the best pics I could take. Any ideas?! Thank you in advance or any help.

RE: Small caterpillars eating leaves

Those sure look like webworms (also called "bagworms" because of the white bag-like nests seen around the joints of stems and leaves). Rare to see them on tomatoes but if the area is badly infested with them it is possible. Cool wet weather also encourages them.

You need an insecticide called Bacillus Thuringiensis (BT) which comes in dust or liquid. Liquid bacillus best in this case I think for full coverage. Try to spray quickly or they will kill the plants.

PS: you can find a great deal of info on webworms on the web (no pun intended) and learning how to recognize the nests and about fall controls for them will really help prevent spring problems.
