Rare
Under 5% of wildlife watchers report a Common Case Moth sighting in Melbourne on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 670th 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 Common Case Moth in Melbourne on a given day, so our monthly data shows no clear season.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Common Case Moth sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Only Melbourne, in our data
Melbourne is the only city on Wallace's Line with enough records to rate Common Case Moth sightings: under 5% of wildlife watchers there report one on a given day.
Same family: Psychidae
The closest relatives of the Common Case Moth that you can see in Melbourne (family Psychidae, Bagworm Moths) are Saunders' Case Moth (about 10%), Ribbed Case Moth (about 10%) and Australian Bag Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Case Moth is recorded against all the insects logged in Melbourne (8 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.
