Although common, Mullein Moths often go unnoticed when adults. It's the caterpillars which gardeners see the most. Mullein Moth caterpillars are easy to spot on plants because of their vivid colours. The white caterpillars are covered in yellow and black markings. They chew the leaves and flowers, sometimes stripping plants when infestations are particularly bad. C. verbasci favours Mullein, but sometimes will be found eating Buddleia and Figworts. As adult moths, they're food for a variety of other wildlife, such as birds, mammals and predatory insects. Mullein Moths are frequent to gardens, meadows, grasslands, waste ground, and woodland, and most active between April and July.
