Variation in floral traits including odor, color and morphology, demonstrate the selective pressures imposed by specific pollinator taxa, such as insects and birds. In southern Arizona, Manduca sexta (Sphingidae) hawkmoths are associated with Datura wrightii (Solanaceae) at both the larval (herbivore) and adult (nectar feeding) stages. However during most of the summer Manduca feeds on "bat-adapted" Agave spp. (Agaveacea) flowers, and only use Datura when it is at peak bloom. Manduca's nectar… CONTINUE READING
