I got so close to this Monarch Butterfly that my lens was almost touching him. He was very patient with me.
The difference in lighting as a cloud passes over the sun clearly affects the brilliance of the wing color in comparing the first and second images in this post.
"The annual migration of North America’s monarch butterfly is a unique and amazing phenomenon. The monarch is the only butterfly known to make a two-way migration as birds do. Unlike other butterflies that can overwinter as larvae, pupae, or even as adults in some species, monarchs cannot survive the cold winters of northern climates. Using environmental cues, the monarchs know when it is time to travel south for the winter. Monarchs use a combination of air currents and thermals to travel long distances. Some fly as far as 3,000 miles to reach their winter home!"
WOW! What an amazing and beautiful world!
