Cottony cushion scale are sap sucking insects with protective coverings that can be found attached to plant leaves and stems.
Cottony cushion scale are sap sucking insects that have protective coverings. The protective covering can be hard and waxy to soft and foam-like. The shield like protective cover or frothy covering can make it difficult to identify them as insects. Cottony cushion scales are commonly brown/black with a grey or white cotton wool like covering when they produce eggs.
Cottony cushion scale insects fix themselves to leaves and stems and suck sap. Their waste products are a sweet honeydew that ants and wasps will feed on readily. The sticky honeydew will also encourage moulds such as sooty mould. It may be difficult to see the scale if they are covered by the mould. Infested leaves usually turn yellow. Some scale live beneath bark and are not easily seen.
