Under 5% of wildlife watchers report a Black Firetail sighting in Blue Mountains National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 681st most-seen of the 789 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.
December and January
In those months about 10% of wildlife watchers report a Black Firetail in Blue Mountains National Park on a given day, against under 5% in February to November, the lowest months.

GBIF citizen-science records
It is estimated from how often the Black Firetail is recorded against all the insects logged in Blue Mountains National Park (5 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.
