In 3 days ~20% in a week ~40%
Stenoptilia zophodactylus, also known as the dowdy plume, is a species of moth of the family Pterophoridae found worldwide. It was first described by Philogène Auguste Joseph Duponchel in 1840. The wingspan is 16–23 mm. Gielis, C., 1996 provides a description.
The moth can be found from July to September in two or more overlapping broods. Larvae can be found from March to September, initially in an irregular, full depth blotch which may occupy the entire leaf. The frass is in numerous, dispersed brown grains. Some larvae leave the mine during an early instar and feed externally on flower buds and developing fruits while others remain in the mine until shortly before pupation. The larvae feed on common centaury (Centaurium erythraea), Centaurium venusta and Centaurium littoralis, yellow-wort (Blackstonia perfoliata), great yellow gentian (Gentiana lutea), German gentian (Gentianella germanica), Gentianella diemensis, Sopubia trifida and Ngai camphor (Blumea balsamifera).
It is found in Europe, North America (including Mexico), South America (Ecuador and Paraguay), Australia, New Zealand, South Africa, India and Iran. Wikipedia →

With luck
About 10% of wildlife watchers report a Dowdy Plume Moth sighting in Great Otway National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 146th most-seen of the 418 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.
April, August and October–February
In those months about 10% of wildlife watchers report a Dowdy Plume Moth in Great Otway National Park on a given day, against under 5% in March, May–July and September, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Dowdy Plume Moth 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.
2nd of 3
Of the 3 parks where we can rate Dowdy Plume Moth sightings, Great Otway National Park ranks 2nd at about 10%. The best odds are in Booderee National Park (Australia, about 20%).
GBIF citizen-science records
It is estimated from how often the Dowdy Plume Moth is recorded against all the insects logged in Great Otway National Park (15 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.
