Abstract: The notion of pollination syndromes has become a contentious issue within the discipline of pollination ecology (Faegri and van der Pijl, 1979; Waser et al., 1996). The predictability of pollinators based upon floral trait suites in particular has been challenged. In this study, the role of bumblebees, noctuid moths and other pollinators of Silene stellata are examined in terms of the selective pressures they exert on combinations of floral color and inflorescence height. Experimental runs were performed using individual plants manipulated to exhibit one color treatment (red, pink and white) in combination with a height treatment (short, tall). The frequency of insect visits and approaches were then calculated and used as an estimate of the selective pressures the pollinator guilds are exerting on the plant. After excluding bumblebees from the analysis because of a low sample size, PROC Catmod (SAS vs. 8.e) was utilized to analyze the data. The analysis revealed that noctuid moths show no preference for color or height, while the small hymenoptera and diptera pollinator guild show a significant preference for floral color. These results can be interpreted as a challenge to the pollination syndrome concept, as the noctuid moths showed no preference for white floral color, a trait typically associated with a nocturnal moth pollination syndrome. The small hymenoptera and diptera also contrast their typically perceived role as extreme generalists.
