Twinkling Solar Butterfly Rock Twinkling Solar Butterfly Rock has 5 separate butterflies on flexible stems that can be bent to create an eye-catching display. Add a magical look to your outdoor landscaping when you display this whimsical accent among the plants and flowers in your garden. Each butterfly has a white LED light that twinkles in a pattern, so different ones light up at different times for a beautiful effect. A solar panel on the rock stores the sun's energy during the day to power the lights after dark. The plastic butterflies are attached to the cold cast ceramic rock with flexible wiring.
