With luck
About 10% of wildlife watchers report a Ribbed Case Moth sighting in Sydney on a given day, based on 69 verified sightings from GBIF citizen-science data. It is the 140th 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 30%, if each day is a fresh chance.
February–April, June–July, September and November
In those months about 10% of wildlife watchers report a Ribbed Case Moth in Sydney on a given day, against under 5% in May, August, October and December–January, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Ribbed Case Moth sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Among the best
Of the 4 cities where we can rate Ribbed Case Moth sightings, Sydney ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Melbourne (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Ribbed Case Moth is recorded against all the insects logged in Sydney (69 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.
