Leistarcha scitissimella is a moth of the family Xyloryctidae. It is found in Australia, where it has been recorded from the Australian Capital Territory, New South Wales and Queensland. The wingspan is about 31 mm. The forewings are dark fuscous, very closely strewn with very elongate whitish scales. All veins and extreme the costal margin are slenderly whitish and there is a clear dark fuscous streak above the cell from the base to before the middle, then obscurely continued between the veins to the costa before the apex. There is a dark fuscous-streak beneath the cell almost from the base to the middle and a sharply defined dark fuscous streak from the middle of the disc to the hindmargin beneath the apex. There is also a slender dark fuscous streak along the inner margin from near the base to the middle of the hindmargin, broader on the anal angle and then attenuated, sharply interrupted by the veins. The hindwings are fuscous-grey, rather lighter towards the base.
The larvae feed on Eucalyptus amygdalina beneath loose bark attaching cut leaves to entrance. They are greyish-fuscous, anteriorly lighter and more greenish. Wikipedia →

With luck
About 10% of wildlife watchers report a Leistarcha scitissimella sighting in Blue Mountains National Park on a given day, based on 34 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 102nd most-seen of the 789 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
November and December
In those months about 20% of wildlife watchers report a Leistarcha scitissimella in Blue Mountains National Park on a given day, against under 5% in May to October, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Leistarcha scitissimella 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 2 parks where we can rate Leistarcha scitissimella sightings, Blue Mountains National Park has the highest daily chance: about 10%. Next come Great Otway National Park (Australia, about 10%).
GBIF citizen-science records
It is estimated from how often the Leistarcha scitissimella is recorded against all the insects logged in Blue Mountains National Park (34 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.
