What anecdotal observation suggests a preference in the color of flowers visited by B. flavidus?
Answer
A preference for purple-hued flowers.
Although *Bombus flavidus* is generally categorized as a forager generalist visiting an extensive range of plant species across North America and Eurasia, certain anecdotal observations regarding specific floral traits have been recorded. Among these non-exhaustive notes is a suggestion that the queens exhibit a preference for flowers that possess a purple hue. While the primary driver for visitation remains the abundance and accessibility of nectar, this color inclination might subtly influence immediate foraging site selection when multiple nectar sources are available to the queen, perhaps aiding in quicker identification of viable carbohydrate supplies.
