Painted Lady Butterflies (Lepidoptera: Vanessa cardui) - Back on Week 6, we posted information and links related to the adult. UPDATE - This week, Alberta Agriculture & Forestry reminded their network of cooperators to watch for V. cardui larvae because the species has a broad host range and can feed on soybean (Action threshold=>25% defoliation), sunflowers, borage and dry beans in addition to several species of thistles (including Canada thistle) and mallow.
