Beautiful butterflies!

Butterflies go fluttering by on colored wings that catch the eye, on wings of orange, and silvery blue, on wings of golden yellow, too.  Butterflies float in the air making their homes most anywhere:  the rain forest, fields, and pasture land, on mountaintops, and desert sand.  If winter brings the cold and snow, to warmer climates, off they go.  Returning home the following spring, beautiful butterflies, on the wing!            (author unknown)
