Ctenoplusia albostriata, the eastern streaked plusia, is a moth of the family Noctuidae. It is found in India, Sri Lanka, eastern Asia and the Pacific, including Borneo, Hong Kong, Vietnam, Japan, most of Australia and New Zealand.
This species was first described by Otto Bremer and William Grey in 1853 and originally named Plusia albostriata. George Hudson, in his 1928 book The butterflies and moths of New Zealand, described and illustrated this species under the name Plusia oxygramma.
The wingspan is about 30–42 mm. Palpi with short third joint. Hind femur of male not tufted with long hair. Head and thorax and forewings are full brown with a grey tinge. Sub-basal, antemedial and postmedial waved lines are brownish and indistinct. Orbicular narrow, elongate and brownish with white edges. There is a white streak found on median nervure conjoined to a brown streak with pale edges on vein 2, terminating at the postmedial line. A dark dentate submarginal line present. Hindwings fuscous with pale base.
The larvae feed on various plants, including Conyza bonariensis and several other Asteraceae species, as well as Dichrostachys cinerea. Other recorded food... Wikipedia →

With luck
About 10% of wildlife watchers report an Eastern Streaked Plusia sighting in Auckland on a given day, based on 20 verified sightings from GBIF citizen-science data. It is the 264th most-seen of the 689 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 30%, if each day is a fresh chance.
February–April, June–July and December
In those months about 10% of wildlife watchers report an Eastern Streaked Plusia in Auckland on a given day, against under 5% in January, May and August–November, the lowest months.
Yes
Of the 4 cities where we can rate Eastern Streaked Plusia sightings, Auckland has the highest daily chance: about 10%. Next come Tokyo (Japan, under 5%) and Osaka (Japan, under 5%).
GBIF citizen-science records
It is estimated from how often the Eastern Streaked Plusia is recorded against all the insects logged in Auckland (20 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.
