Hydrangea Scale Insect - Pulvinaria hydrangeae
Pulvinaria hydrangeae scales affect a whole range of trees and shrubs and are often found on the underside of leaves. The whitish ovisac, up to 10 mm in length, is formed in the months of June to August and is elongated with three clear furrows. Often a female drops off after the eggs have been deposited, leaving only the ovisac on the leaf.
