The mullein moth (Cucullia verbasci) is a medium-sized noctuid moth, wingspan 45–56 mm, whose bark-streaked grey forewings give resting adults near-perfect camouflage against dead stems. Its larvae — among the most distinctive caterpillars in Europe, patterned in vivid yellow, black, and white — feed conspicuously on the leaves of mulleins (Verbascum) and figworts (Scrophularia), and in gardens also on buddleja (Buddleja), frequently stripping plants to bare stems. The species has a Palearctic distribution across western, southern, and central Europe and North Africa, extending east to western Afghanistan; it occupies dry, warm open habitats including gardens where Verbascum or Buddleja are grown. Adults fly from April to June in a single annual generation.
