s (''Digitalis'' species). After hatching the larva bores through the side of the flower, sealing the mouth with silk and feeding on the reproductive parts of the flower, i.e. the stamen and developing seeds. Larva can be found from June to August by searching for discoloured flowers. The pupa overwinters in the soil, lasting through the winter to May and June. The corolla of the flower can persist on a plant long after uninfested flowers have fallen. Somewhat surprisingly, given this very specialized feeding ecology, it has also been recorded feeding on ''
