Orocrambus flexuosellus is a species of moth in the family Crambidae. It was first described by Edward Doubleday in 1843. O. flexuosellus is endemic to New Zealand. It has been recorded from the North Island, South Island and the Stewart Islands. The species' habitat consists of lowland to alpine grasslands.
The wingspan is 19–26 mm. Adults have been recorded on wing from November to February. Adults are nocturnal but are easily disturbed during daylight hours. The larvae are polyphagous, feeding on various grasses and sedges. Adults are attracted to light and have been collected via a mercury vapour light trap. The adult moths have been shown to pollinate Cassinia fulvida, Dracophyllum acerosum, Hoheria lyallii and Olearia virgata. Wikipedia →

Possible
About 20% of wildlife watchers report a Common Grass Moth sighting in Auckland on a given day, based on 272 verified sightings from GBIF citizen-science data. It is the 14th most-seen of the 689 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
April and October–November
In those months about 30% of wildlife watchers report a Common Grass Moth in Auckland on a given day, against under 5% in August, the lowest month.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Common Grass Moth sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is most active around dawn and dusk.
Only Auckland, in our data
Auckland is the only city on Wallace's Line with enough records to rate Common Grass Moth sightings: about 20% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Common Grass Moth is recorded against all the insects logged in Auckland (272 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.
