Dictyophorus spumans, also known as the koppie foam grasshopper, is a species of grasshopper in the family Pyrgomorphidae, indigenous to southern Africa. The name “foam grasshopper” derives from the insect’s ability to produce a toxic foam from its thoracic glands, using a combination of hemolymph with air from the grasshopper’s spiracles. Adult males are typically 4.5 to 5 cm (1.8 to 2.0 in) long and females typically 5 to 7 cm (2.0 to 2.8 in), but can grow up to a length of 8 cm (3.1 in).
