…you may as well do this:
Scale insects are masters of the sap-sucking lifestyle. It is an easy living- all the food a little bug could ask for- with one catch. Scale are a sitting target. Since they can’t run, scale insects must defend themselves from predators in other ways. Recruiting an ant army, building armored shells, or perhaps even sprouting a wild waxy barrier.
I suppose the fluff fence must work, even it does look silly.
*update* Reliable sources on facebook and in the comments suggest that these are not true scale but whiteflies, a related group of sternorrhynchan insects with a similarly sedentary sap-sucking life stage.
