I've noticed that they aren't all that found of cabbage in my garden either. They chew on it some, but they seem to prefer broccoli, cauliflower, brussels sprouts, and even kale. Both the cabbage looper moth caterpillars and the cabbage butterfly caterpillars. I very rarely find them actually on the cabbage, even when there's something like broccoli right next to the cabbage completely infested with them.
