Caterpillars- are these guys good or evil?
Hi, suddenly this morning my husband and I discovered 8 three inch caterpillars climbing up the stucco of the Western exposure on our house. We're fairly new gardeners and we haven't seen caterpillars before. They're black and brownish red. I'm going to try to attach pictures because I'd appreciate your help identifying if these are good witch caterpillars or bad witch caterpillars (Wizard of Oz reference there).
We're in Los Angeles, zone 10b, if that tells you anything.
