Trigonodes hyppasia, the triangles or semi-looper, is a moth in the family Erebidae. The species was first described by Pieter Cramer in 1779. It is largely cosmopolitan, found throughout Borneo, Fiji, India, Maldives, Nepal, Sri Lanka, São Tomé and Príncipe, Taiwan, Thailand, Zimbabwe, northern Australia, and almost all African countries.
The moth family Noctuidae are mostly classified in the family Erebidae now, along with all of the former members of the families Arctiidae and Lymantriidae. This re-classification has not yet met with general consensus, and many resources and publications still follow the older classification scheme.
The wingspan is about 30–46 mm. Antennae of male ciliated. Mid and hind tibia hairy. Body pale ochreous brown, slightly suffused with fuscous or dark grey brown. Forewings with a large black white-edged triangular patch easily distinguished below the cell from near base to towards outer angle. A similar smaller patch found beyond the cell on vein 5, with some pale fulvous behind it. A slightly sinuous submarginal pale line with patches of black suffusion found inside it and a series of black specks beyond it. A dark marginal... Wikipedia →

With luck
About 10% of wildlife watchers report a Triangles sighting in Daintree National Park on a given day, based on 13 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 306th most-seen of the 856 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.
June and October
In those months about 20% of wildlife watchers report a Triangles in Daintree National Park on a given day, against under 5% in May and November–February, the lowest months. Those are among Daintree National Park's driest months, with about 65 mm of rain a month against 380 mm in January.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Triangles sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
4th of 7
Of the 7 parks where we can rate Triangles sightings, Daintree National Park ranks 4th at about 10%. The best odds are in Kanha National Park (India, about 20%), Lamington National Park (Australia, about 20%) and Kruger National Park (South Africa, about 10%).
Same family: Erebidae
The closest relatives of the Triangles that you can see in Daintree National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Asian Magpie Moth (about 20%), Asota orbona (about 20%) and Imperial Fruit Sucking Moth (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Triangles is recorded against all the insects logged in Daintree National Park (13 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.
