Skeletonized Swamp White Oak Leaf - Quercus bicolor
I found several leaves that were completely skeletonized. I'm not sure if it was caused by insects or some injury. I assume it's an injury - maybe caused by a cold snap when the leaves were still in bud? Or, is it just how some leaves decay over time? I'm not sure.
Habitat: Deciduous forest
''Quercus bicolor'', the swamp white oak, is a North American species of medium-sized trees in the beech family. It is a common element of America's north central and northeastern mixed forests. It can survive in a variety of habitats. It forms hybrids with bur oak where they occur together in the wild.
