Mnesictena flavidalis is a moth in the family Crambidae. It was described by Edward Doubleday in 1843. It is endemic to New Zealand. This species was first described by Edward Doubleday in Ernst Dieffenbach's book Travels in New Zealand: with contributions to the geography, geology, botany and natural history of the country and named Margaritia flavidalis. In 1899 Hampson placed this species in the genus Mnesictena. In 1983 G. E. Munroe synonymised the genus Mnesictena with Udea. However, in 1988 John S. Dugdale treated Mnesictena as a valid genus. Dugdale's treatment was followed in 2011 by Richard Mally and Matthias Nuss. The male holotype specimen, collected in Auckland by A. Sinclair, is held at the Natural History Museum, London.
Doubleday described this species as follows: All the wings ochraceous, the outer margins with a series of minute dots. Anterior wings with a faint striga near the base, a still fainter one near the middle, and a more distinct much-waved one near the outer margin, and two discoidal stigmatiform spots fuscous. Posterior wings with a discoidal spot, preceded towards the anterior margin by a smaller one, a transverse striga... Wikipedia →

With luck
About 10% of wildlife watchers report a Rusty Dotted Triangle sighting in Egmont National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 123rd most-seen of the 191 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.
March and May
In those months about 20% of wildlife watchers report a Rusty Dotted Triangle in Egmont National Park on a given day, against under 5% in February and June–December, the lowest months.
Between 6 and 9 pm
Across all the parks we cover, that three-hour window holds the most Rusty Dotted Triangle sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Only Egmont National Park, in our data
Egmont National Park is the only park on Wallace's Line with enough records to rate Rusty Dotted Triangle sightings: about 10% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Rusty Dotted Triangle is recorded against all the insects logged in Egmont National Park (6 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.
