It doesn't need to be cabbage they are feeding on but they seem to love feeding on my young alyssum too and I am just so annoyed. I only have 2 seeds out of a hundred that germinated and they are feeding on its leaves. Every other day I have to constantly check and few days before that, I could remove one caterpillar everyday with their poops on the leaves too.
I found a video that would probably help me in the following days.
I certainly don't like chemicals on my plants and I wanted to remove these pests in the most natural way I could.
