Scoparia chiasta is a moth in the family Crambidae. It is found in Australia, where it has been recorded from New South Wales. This species was named by Edward Meyrick in 1884. Meyrick went on to give a full description of the species in 1885.
The wingspan is 14–17 mm. The forewings are white, irrorated (sprinkled) with fuscous and dark fuscous and with a short dark fuscous streak from the base of the costa parallel to the inner margin. The first line is white, posteriorly margined with dark fuscous. The second line is white, margined with dark fuscous. The hindwings are pale whitish grey, greyer on the hindmargin and towards the apex. Adults have been recorded on wing from May to August. Wikipedia →

Under 5% of wildlife watchers report a Scoparia chiasta sighting in Brisbane on a given day, based on 23 verified sightings from GBIF citizen-science data. It is the 463rd most-seen of the 1083 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.

GBIF citizen-science records
It is estimated from how often the Scoparia chiasta is recorded against all the insects logged in Brisbane (23 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.
