It beckons. What makes sugar water, the human-offered replacement for nectar, so irresistible? Hummingbirds are drawn to feeders with sugar water. Honeybees, Wasps, and Bumblebees swarm to those same feeders. And, on our last morning in Madera Canyon, a lone Swallowtail Butterfly spent quite some time drinking with its long straw-like proboscis at one of the feeders. Most of the time I watched, its wings were closed and it was facing me so I couldn’t see the pattern of the wings. Finally, it fluttered to the next portal so I could see and appreciate the intricate, colorful, and delicate pattern of its wings. I have read that Butterflies find their nectar by its smell.
