Why do bees seldom rest on grass flowers?

Bees seldom rest on grass flowers because these flowers typically lack the nectar and pollen that bees seek for nourishment. Grass flowers are often wind-pollinated, relying on air currents rather than insects for pollination, which makes them less attractive to bees. Additionally, the structure of grass flowers is not conducive to bee foraging, as they are usually small and inconspicuous compared to more colorful, nectar-rich flowering plants.
