Scolypopa australis, commonly known as the passionvine hopper, is a species of insect in the Ricaniidae family of planthoppers (Fulgoroidea) that is native to Australia and was introduced to New Zealand. Despite its name, they are found not only on passion vines, but on many plant species, including kiwifruit and 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 were first recorded in New Zealand in 1878, where they are among over 40 species of planthopper, mostly native, but including the introduced Siphanta acuta (green planthoppers), Achilus flammeus (red fingernail bugs) and Anzora unicolor (grey planthoppers), all from Australia. They may be a vector of the 'sudden decline' disease caused by Phytoplasma australiense that has affected the native cabbage tree (Cordyline australis), and... Wikipedia →

With luck
About 10% of wildlife watchers report a Passionvine Hopper sighting in Sydney on a given day, based on 156 verified sightings from GBIF citizen-science data. It is the 82nd most-seen of the 742 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Passionvine Hopper in Sydney on a given day, against under 5% in April to October, the lowest months.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Passionvine Hopper sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 5
Of the 5 cities where we can rate Passionvine Hopper sightings, Sydney ranks 4th at about 10%. The best odds are in Auckland (New Zealand, about 30%), Melbourne (Australia, about 20%) and Hobart (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Passionvine Hopper is recorded against all the insects logged in Sydney (156 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
