In the spring, we commonly see butterflies 'mud-puddling', or flocking to wet, muddy trails and roadsides. These insects are collecting liquid from puddles to obtain important nutrients, which are vital to their health and reproduction. Help protect Yosemite's pollinators and step with care. | Yosemite National Park | Facebook
