The larvae feed on a wide variety of plants, including the flower heads of composite flowers and other flowering plants, as well as shrubs and trees. Recorded food plants include Aster, Rudbeckia, Liatris, Solidago, Artemisia, Achillea and Rubus species. They attach bits of the plant tissue on which they are feeding along their backs. The species overwinters as a partially grown larva.
