In 3 days ~10% in a week ~20%
Cardiaspina fiscella, the brown basket lerp or brown lace lerp, is a jumping plant louse species in the genus Cardiaspina originally found in Australia. It spread to New Zealand where it was found in 1996 near the Auckland airport. It feeds on eucalyptus, especially swamp mahogany, and is found in Victoria, eastern New South Wales, and southeastern Queensland, as well as the capital territory (ACT) around Canberra and on Norfolk Island. Cardiaspina fiscella has five nymphal instars, and as the instars moult they add a layer to their outside covering (casing), known as the "lerp". Wikipedia →

Rare
Under 5% of wildlife watchers report a Cardiaspina fiscella sighting in Melbourne on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 583rd most-seen of the 875 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Cardiaspina fiscella in Melbourne on a given day, so our monthly data shows no clear season.
Among the best
Of the 2 cities where we can rate Cardiaspina fiscella sightings, Melbourne ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Auckland (New Zealand, under 5%).
GBIF citizen-science records
It is estimated from how often the Cardiaspina fiscella is recorded against all the insects logged in Melbourne (11 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.
