Beautiful Cabbage Moth

I saw this wonderful article from the UCCE Master Gardeners of Santa Clara County and thought I would share it - every garden around here has those pretty white moths fluttering around….

Cabbage Family

Aren’t those little white butterflies flitting around your garden beautiful? Well, not if you know what they are or if you have noticed corresponding holes in your collard greens. They are the adult moth stage of the cabbageworm which eats cruciferous vegetables. Included targets are kale, cabbage, broccoli, and bok choi. You can catch the moths with a butterfly net or pool skimmer before they can lay more eggs. You can hand pick the well-camouflaged one-inch-long green caterpillars or spray them with an organic product with the active ingredient of Bacillus thuringiensis (Bt). You can even pick off the tiny white eggs if you can find them on the undersides of the leaves.
