The impact of floral spot and ring markings on pollinator foraging dynamics

Linear areas of contrasting floral colour, or “nectar guides”, are recognized to enhance pollinator attraction. Few studies, however, have investigated the role of other types of floral marking in pollinator behaviour. In this study, we explore the impact of petal spots and petal rings on bumblebee foraging dynamics. Using model flowers with discrete spot or bullseye ring patterns we investigate the responses of Bombus terrestris foragers...
