With luck
About 10% of wildlife watchers report an Australian Alfalfa Moth sighting in Blue Mountains National Park on a given day, based on 12 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 359th most-seen of the 789 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.
March and August–November
In those months about 10% of wildlife watchers report an Australian Alfalfa Moth in Blue Mountains National Park on a given day, against under 5% in April–July and December–February, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Australian Alfalfa Moth sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Blue Mountains National Park, in our data
Blue Mountains National Park is the only park on Wallace's Line with enough records to rate Australian Alfalfa Moth sightings: about 10% of wildlife watchers there report one on a given day.

GBIF citizen-science records
It is estimated from how often the Australian Alfalfa Moth is recorded against all the insects logged in Blue Mountains National Park (12 verified sightings from 2019 to 2026), 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.
