Cottony cushion scale, Fluted scale (Eng.), Australiese wolluis (Afr.)
These bugs secrete honeydew which can result in sooty mold. Most damage on the host plants is a result of sap depletion.
This species is a common cosmopolitan pest which originated from Australia. Females are easily recognized by the white, fluted attached egg sacs. Females can lay eggs without the need to mate with males - a self-fertilizing hermaphrodite.
