I'm intrigued by the idea of things unseen but existent. Often, the difference amounts to perspective and even lens. The black-eyed susan, a tall native flower with yellow petals surrounding a "black eyed" center, attracts bees. The bees perceive light in the ultra-violet spectrum, seeing things we do not see. Each black-eyed susan features nectar guides, near the center of each petal, to guide the bees which pollinate the flower to the nectar within the flower. Birds, too, have the ability to see in the ultra-violet ranges, while we people see in a mere three dimensions of light. Newborn stars emit ultra-violet light which illuminates nebulae.
I like that ultra-violet light lives up to its moniker. It is so blue that people cannot see it. I like also that the same chemicals which make a flower ultra-violet and hence, attractively visible to pollinating bees, also serves as a kind of natural insecticide for would-be devouring creatures. Bats use ultra-violet light to find attractive flowers in the dark. Some research suggests that the Australian crab spider even takes advantage of the bees' attraction to ultra-violet markings by positioning itself in an "attractive way" on such flowers.
Bees land on the crab-spider-posed flowers mroe frequently, though they therefore become more likely to be
The Gloriosa Daisy is a variety of the black-eyed susan which features ample splashes of red surrounding the black-eyed center of the flower. Burpee Seed Company developed the cultivar, using a chemical derived from the crocus plant to shock the black-eyed susan into a new and unexpected color pattern. Bees lack good color vision as to red. Red flowers ordinarily attract birds rather than bees. But the Gloriosa Daisy features ample bursts of glorious red.
Sir William Herschel first discovered the infrared light spectrum in 1800. Herschel said something with which I strongly agree: "If I were to pray for a taste which would stand by me under every variety of circumstances, and be a source of happiness and cheerfulness to me through life, and a shield against its ills, however things might go amiss, and the world frown upon me, it would be a taste for reading.".
I love that I can set off on a quest about one thing, and it leads me to another thing, and before I know it, I am pausing for a third, fourth and fifth thing, and somehow, in my mind, they are all one thing, a kind of unified field thing, and they are all radiating in light spectra and, as blooming facts and jasmine often do, opening to me in luxuriant visible light yellow night-time displays.
