The flowers use coordinated signals of color and fragrance to attract insects, which acquire pollen during floral visits and ensure pollination of the plants. In turn, the insects benefit by acquiring nectar and pollen as food.
By connecting visual and olfactory channels, the flowers render their signal stronger and more stable under the intense environmental conditions of the Aegean. On windy days, fragrances may dissipate but colors will remain viable floral attractants, whereas fragrance could be the primary attractant when flowers are concealed by the dense vegetation of the Phrygana scrublands.
