Q:What is that white fluffy stuff on my trees?

A:  The melaleuca psyllid exudes a waxy filament from its body as it feeds. Officially called flocculence, this waxy material is bright white, like cotton. It blows away easily and dissolves when you touch it. Throughout most of the year it is not too noticeable, but it can build up during dry spells. It is harmless and washes away easily with the rain or with a hose.
