Monarch ButterflyA Monarch butterfly in Pacific Grove, Calif. When we lived in Cupertino, Calif., I often visited the Pacific Grove Monarch Sanctuary that is a temporary home to Monarch butterflies each late fall to early spring (times can vary). Locals told me that the butterflies are many fewer than there used to be decades ago. I have some single shots of butterflies that I will be adding. So far, I only have one.
