Species details:

Note: Larvae and nymphs of this species are highly gregarious. While feeding on the sap of certain tree species they excrete a foamy liquid that forms protective nests around them. Numbers of these nymphs can by so high in a single tree that the excessive excretions can drip onto the soil below the tree and may form wet patches or even small puddles.
Distribution: Widespread in tropical and Southern Africa.
