A variety of caterpillars cause damage in Michigan cole crops. The three most significant species are the imported cabbageworm (Pieris rapae, Lepidoptera: Pieridae), the diamondback moth (Plutella xylostella, Lepidoptera: Plutellidae) and the cabbage looper (Trichoplusia ni, Lepidoptera: Noctuidae). These three species are commonly found on cole crops such as cabbage, cauliflower, broccoli, collards, turnips, radishes, kale, mustards and other leafy greens.
