Butterflies, which delight in bright colors and distinct markings, find little to charm them here; but the pale shade of pink or white, easily distinguished in the dark, and the fragrance, strongest after sunset, effectively advertise the flower at dusk when its benefactors begin to fly. The sphinx moth, a frequent visitor, works as rapidly in extracting nectar from the deep tube as any hawk moth, so frequently mistaken for a hummingbird. The little cliff-dwelling bees (Halictus), among others, visit the flowers by day for pollen only. At first five outer stamens protrude slightly from the flower and shed their pollen on the visitor, immediately over the entrance. Afterward, having spread apart to leave the entrance free, the path is clear for the five inner stamens to follow the same course. Now the styles are still enclosed in the tube but when there is no longer fear of self-fertilization - that is to say, when the pollen has all been carried off, and the stamens have withered - up they come and spread apart to expose their rough upper surfaces to pollen brought from younger flowers by the moths.

The true pinks of Europe, among which are the SWEET WILLIAM or BUNCH PINK (D. barbatus) of our gardens, occasionally wild here, and the deliciously spicy CLOVE PINK (D. Carophyllus), ancestor of the superb carnations of the present day, that have reached a climax in the Lawson pink of newspaper fame, were once held sacred to Jupiter, hence Dianthus = Jove's own flower. The Deptford pink, a rather insignificant little European immigrant, without fragrance, has a decided charm, nevertheless, when seen in bright patches among the dry grass of early autumn, with small butterflies, that are its devoted admirers, hovering above.
