My sis lives in Oklahoma... 20+ years. She has discovered that what she thought was a white mold on some of the outdoor plants is actually some sort of insect. It appears on the stems of plants, 1 to 2 inches long, and is fluffy white in appearance. When she got a much closer look, she could see the little fluffy fellows in their little fluffy white nest and they can jump pretty high. In fact, she said that's all they do... jump. Please Help!! Can anyone help identify these little creatures?
