Euchaetis rhizobola is a moth of the family Oecophoridae. It is found in Australia, including New South Wales, Queensland, the Australian Capital Territory, Victoria, South Australia and Western Australia. The wingspan is 31–33 mm. The forewings are ferruginous, irrorated with very pale greyish-ochreous and with very pale greyish-ochreous; markings and a rosy costal edge. There is a short streak along the base of the inner margin, forming a spot at the base and a moderate rather irregular-edged costal streak, rather broad at the base, emitting two irregular oblique wedge-shaped projections, at one-fourth and the middle, first running to the fold before middle, the second to a whitish dot in the disc at three-fifths. There are three ill-defined grey-whitish dots beneath the posterior half of the costal streak, almost confluent with it and there is a grey whitish submarginal line, becoming marginal on the lower half of the hindmargin and with the anterior edge waved. The hindwings are pale whitish-ochreous, yellowish-tinged and with the apex more ochreous-yellowish, sometimes slightly rosy-tinged. Wikipedia →

With luck
About 10% of wildlife watchers report a Euchaetis rhizobola sighting in Blue Mountains National Park on a given day, based on 16 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 294th 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 40%, if each day is a fresh chance.
September
In that month about 30% of wildlife watchers report a Euchaetis rhizobola in Blue Mountains National Park on a given day, against under 5% in November to July, the lowest months. That is one of Blue Mountains National Park's driest months, with about 50 mm of rain against 150 mm in March.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Euchaetis rhizobola sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 2 parks where we can rate Euchaetis rhizobola sightings, Blue Mountains National Park ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Springbrook National Park (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Euchaetis rhizobola is recorded against all the insects logged in Blue Mountains National Park (16 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.
