''Scolypopa australis'', commonly known as the passionvine hopper is a species of planthopper in the insect family Ricaniidae found in Australia. Despite their name, they are found not only on passion vines, but on many different plant species such as the lantana. Brown with partly transparent wings, they are about 7mm long as adults and 5mm as nymphs. As an adult they look somewhat like a moth to the untrained eye, and walk "like a ballerina". The nymphs are wingless and are informally known as fluffy bums. When sufficiently aroused they will hop off their plant "with a 'snap'". Like all planthoppers they suck plant sap. This leaves a honeydew secretion which bees gather. They are also known to cause honey poisoning.
