Furthermore, the question is addressed whether the adult butterflies act as pollinators on the larval host plants (DeVries, 1997) and therefore could be regarded as an example of coevolutionary and mutualistic pollinatoreplant interaction, as reported for senita moths (Fleming and Holland, 1998; Holland and Fleming, 2002) and yucca moths (Pellmyr, 2003; Pellmyr and Krenn, 2002).
