– M. virginica is pollinated both diurnally and nocturnally, with observations suggesting that bumblebees are the predominant floral visitors (Groman and Pellmyr 1999). Bombus pennsylvanicus and Hemaris diffinis are critical diurnal pollinators; however, diurnally pollinated plants were observed to produce significantly lower seed set than nocturnally and open pollinated plants (Groman and Pellmyr 1999). Hence nocturnal visitors contribute more to M. virginica reproduction despite frequent diurnal visits (Groman and Pellmyr 1999).
