Attractiveness of floral traits to diverse pollinators in zygomorphic flowers of <i>Isodon trichocarpus</i> (Lamiaceae)

Abstract When the abundance and composition of pollinators are unpredictable, exploitation a diverse assemblage is important for plant reproduction. To examine role floral traits in attracting pollinators, we performed field study using zygomorphic flowers Isodon trichocarpus. We investigated variation among seasonal pollinator determined whether behaviour linked to traits. compared diversity by flower-based rarefaction extrapolation. Pollinator increased with span corolla opening. The number bumble bee visits upper lip height. During flowering period, there were only 2 days when all groups (wasps, bees, small bees hoverflies) observed, 4 one group was observed. Thus, degree generalization not similar because differed according some observed part season. Our results show that form attractiveness different flower associated visits. this species related
