AbstractIndividuals of the perennial plant Actaea spicata possess an extended and bimodal flowering phenology. This study examined hypotheses aimed at explaining asynchronous flowering. Data from two years show that fruits from early flowers suffer from a 28-30% seed predation caused by a geometrid moth, Eupithecia immundata, whereas fruits from late flowers completely escape seed predation. A. spicata was found capable of self-pollination without reduction in fecundity, but with a slight and significant reduction in seed size. Destruction of early flowers did not enhance the development of late flowers. These results, together with considerations of seed dispersal, suggest that the ''seed predator avoidance hypotheses'' of flowering asynchrony is a contributing explanation of the bimodal flowering phenology in A. spicata.
