In this paper I report components of effectiveness for pollinators of a tropical distylous shrub, Psychotria suerrensis (Rubiaceae), which is visited by a variety of bees, wasps, and butterflies, and by two species of hummingbirds. In the field, I measured the following components of effectiveness: frequency of visits, evenness of visits across plants, and diurnal pattern of visits. I also used flight-cage experiments to compare pollentransfer abilities of euglossine bees and heliconiid butterflies. Euglossine bees visited more frequently, visited earlier in the day, and visited a higher proportion of plants in the population than did other taxa. In flight cage experiments, bees and butterflies transferred similar amounts of pollen overall, but bees transferred significantly more inter-morph (compatible) pollen. For each component measured, euglossine bees appeared to be the most effective pollinators.
在本文中，我报告了一种热带二型花柱灌木——苏氏九节（茜草科）传粉者的有效性组成部分。该植物会吸引多种蜜蜂、黄蜂、蝴蝶以及两种蜂鸟前来访花。在野外，我测量了以下有效性组成部分：访花频率、植株间访花的均匀度以及访花的昼夜模式。我还利用飞行笼实验比较了 Euglossine 蜜蜂和透翅蝶的花粉传播能力。Euglossine 蜜蜂比其他类群访花更频繁，在一天中更早访花，并且访花的植株在种群中所占比例更高。在飞行笼实验中，蜜蜂和蝴蝶总体上传粉量相似，但蜜蜂传递的异型（可亲和）花粉显著更多。对于所测量的每个组成部分，Euglossine 蜜蜂似乎都是最有效的传粉者。
