Insect
Two-lined Spittlebug
Prosapia bicinctaAdult two-lined spittlebugs feed on sap from grasses and shrubs, injecting toxic saliva that causes surrounding plant tissue to yellow and die back. Nymphs produce a dense, protective white foam by pumping air into excreted plant fluids, shielding their delicate bodies from desiccation and predators while feeding near ground level. When threatened, adults rely on powerful hind legs to leap explosively into the air before flying away.
