The mullein moth, Cucullia verbasci, lays its eggs on verbascum, buddleia and figwort at the end of spring. Shortly after, from late spring to midsummer, the caterpillars demolish the foliage. Bad infestations can actually strip a plant. They then hide in the soil to pupate.

The moment you spot an infestation, spray them with pyrethrum. If the plants are in flower, spray in the evening, so pollinating insects aren’t affected.
