Whether this is a bird's or a chicken's downy feathers, I don't know! I just know it is hanging through a strand of a spider web, swaying with the slight wind. The background is a rich color of croton's leaves.
This is a variegated Alternanthera, but that curved leaf i guess is done by a larva or a spider that pulled both leaf edges to hide inside. I've done several intrusions in leaf rolls like this, finding them inside. A spider normally jumps to escape, but a larva just crawls away. Nevertheless, there is beauty in these worlds!
