The sticky white powder is left behind by mealybugs. Mealybugs are little sap-feeding insects that grow waxy filaments as they mature. They often feed in clusters on tender branches,stalks, and the undersides of leaves, where they shed their body filaments onto plant tissues while they exude a sticky, sweet substance called honeydew.
