Under 5% of wildlife watchers report a Casuarina Gall sighting in Sydney on a given day, based on 51 verified sightings from GBIF citizen-science data. It is the 192nd most-seen of the 742 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 30%, if each day is a fresh chance.
June–August and October
In those months about 10% of wildlife watchers report a Casuarina Gall in Sydney on a given day, against under 5% in September and November–May, the lowest months.

Across all the parks we cover, that three-hour window holds the most Casuarina Gall sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 cities where we can rate Casuarina Gall sightings, Sydney has the highest daily chance: under 5%. Next come Brisbane (Australia, under 5%) and Melbourne (Australia, under 5%).
GBIF citizen-science records
It is estimated from how often the Casuarina Gall is recorded against all the insects logged in Sydney (51 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.
