The plant-pollinator ‘arms race’ model posits that a major driver of the evolution of elongated corollas in flowers is reciprocal selection for ‘morphological fit’ between pollinator-tongue length and access distance to nectar (usually coroll

Abstract Adaptations that attract pollinators to flowers are central to the reproductive success of insect‐pollinated plants, including crops. Understanding the influence of these non‐rewarding traits on pollinator preference is important for our
