1. Pollinators visiting large floral displays may probe several flowers in sequence, leading to geitonogamous (among-flower) self-pollination. To investigate the relationship between floral display size and patterns of pollinator movement, we studied foraging by several pollinator species in four replicate arrays of Mimulus ringens (Scrophulariaceae). In each array displays were trimmed to two, four, eight and 16 flowers per plant. 2. Bees preferred large displays, and probed more flowers in sequence on large than on small displays. However, the proportion of available flowers probed decreased with display, resulting in nearly equal floral visitation rates across treatments. 3. Because pollinators probed more flowers in sequence on large displays, plants with numerous flowers should experience more geitonogamous self-pollination than plants with small displays. 4. In all four treatments, pollinators frequently visited …
