Scolypopa australis


Scolypopa australis, commonly known as the passionvine hopper, is a species of insect in the Ricaniidae family of planthoppers that is native to Australia and has been introduced to New Zealand. Despite its name, they are found not only on passion vines, but on many plant species, including the lantana. Brown with partly transparent wings, they are 5–6 mm long as adults and 5 mm 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.

In New Zealand

They arrived in New Zealand in 1876, where they are among over 40 species of planthopper, mostly native, but including the introduced Siphanta acuta, Achilus flammeus and Anzora unicolor, all from Australia. They may be a vector of the 'sudden decline' disease caused by Phytoplasma australiense that has affected the native cabbage tree, and are a common pest in gardens. They are also found in regrowing forest. They are very common in the summer and autumn north of Nelson.
