A ladybug walks along a wild lupine leaf in California's Yosemite National Park. These colorful plants were brought to North America from the Mediterranean as ornamental flora and quickly spread into the wild. The Yosemite varieties usually flower blue and white and grow abundantly in the park's sandy soil.
