Dictyophorus spumans, the koppie foam grasshopper, rooibaadjie, or African foam grasshopper, is a species of grasshopper in the family Pyrgomorphidae indigenous to southern Africa. The name "foaming grasshopper" derives from the insect's ability to produce a toxic foam from its thoracic glands. The foam is created by a combination of haemolymph with air from the grasshopper's spiracles. Its genus Dictyophorus is closely related to Phymateus. Source
