Pollinator abundance, morphology, and flower visitation rate: analysis of the “quantity” component in a plant-poffinator system

Abundance and flower visitation rate of the pollinators of Lavandula latifolia (Labiatae), an insect-pollinated shrub, were studied over a 6-year period. The objective was to elucidate interspecific patterns in the ldquoquantityrdquo component of the plant-pollinator interaction. A total of 54 insec...

Most of this variation was explained by differences in flower handling time (HT). Regardless of proboscis length, hymenopterans had intrinsically shorter handling times than lepidopterans. Within each group, HT decreased exponentially with increasing proboscis length. Abundance and visitation rate were uncorrelated across pollinator taxa.
