Rare
Under 5% of wildlife watchers report a Black Scale sighting in Melbourne on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 480th 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 Black Scale in Melbourne on a given day, so our monthly data shows no clear season.
Among the best
Of the 6 cities where we can rate Black Scale sightings, Melbourne ranks 2nd at under 5%, level with the leaders once rounded. The best odds are in Sydney (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Black Scale is recorded against all the insects logged in Melbourne (16 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.
