Specialized on generalists: attraction characteristics of early spring flowering Trillium cuneatum.

Sweet Betsy (Trillium cuneatum Small.) is one of the earliest plants to flower in the spring and combines a fruity odor with unusually colored wine-red petals. We conducted field studies of Trillium cuneatum from 2009 to 2011. Using direct observation and various trapping methods we determined: 1) the identity of insect visitors to Trillium cuneatum; 2) the characteristics of floral attraction (color, scent); and 3) temporal variation of insect visitors relative to floral display, including flower duration and year-to-year. Our results suggest that Trillium cuneatum is among a floral guild that exhibit a floral syndrome that is functionally specialized and ecologically generalized, attracting a range of non-typical floral visitors.
