CANCER (June 21-July 22): Bees and other insects can see ultraviolet light invisible to humans. When they look at flowers, they detect designs on the petals we cannot. Like, an evening primrose appears totally yellow to us, but it calls seductively to bees with a flashy star pattern in the center. Many secret signs flowers offer pollinators are meant to guide them to the pollen and nectar. This is our weekly metaphor. Not saying you'll perceive a broader spectrum of light, but you'll discern cues and clues hidden from most.
