Ptyelus grossus

Ptyelus grossus is a Auchenorrhynchan spittlebug in the family Aphrophoridae. Occurring from Southern Africa through to West Africa, the species is gregarious in its larval and nymph stages, feeding on a variety of plants, and producing protective nests of acrid foam from the plant's sap. Excreted in large quantities, the foam drips incessantly causing wet patches on the soil below.
