(EGG NESTS & FLAGGING)
Weakened branches often snap in the wind due to the abundance of cicadas depositing their egg nests in limbs the width of a pencil. These dangling limbs resemble flags flapping in the breeze, hence the name. Mature healthy trees are not normally affected but young saplings often receive heavy damage and can die if not given added protection such as tree netting. I recommend not planting saplings a year prior to or during a Brood emergence.
