monarch butterflyDanaus plexippus
For all those years I camped in Morro Bay State Park as a kid during the summers, I never knew there was a significant monarch overwintering site just behind the campgrounds. It was great to see them for my first time. The overwintering numbers are far fewer than in Mexico, so it's not an obvious tourist attraction. They really are difficult to spot in the eucalyptus trees, but once you know they're there... WOW!
