Macrobrochis gigas
In 3 days ~80% in a week >90%
Macrobrochis gigas is a moth of the family Erebidae. It was described by Francis Walker in 1854. It is found in China (Yunnan), India (Sikkim), Bhutan, Nepal, Indonesia, Thailand, Hong Kong and Taiwan. The habitat consists of woodlands.
Adults have been recorded on wing from March to May. There is one generation per year. The species is possibly involved in a mimicry relationship with Eterusia aedea. Macrobrochis gigas differs from congeners in the following morphological characters: orange head and collar; thorax black above with green metallic tinge and orange below; tegulae striped with orange; abdomen greenish black, the extremity and ventral surface orange; abdomen with white bands or lateral spots on the hind borders of each segment; forewing black with a green tinge, with a small white spot at the base, with a larger one beyond it, and a spot at the end of the cell and another below it; hindwing with the basal half white, the outer half black.

Likely
About 40% of wildlife watchers report a Macrobrochis gigas sighting in Taroko National Park on a given day, based on 165 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 12th most-seen of the 447 insects we can rate there. Over three days the chance rises to about 80%, and over a week to over 90%, if each day is a fresh chance.
May and June
In those months about 70% of wildlife watchers report a Macrobrochis gigas in Taroko National Park on a given day, against under 5% in August to March, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Macrobrochis gigas sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Taroko National Park, in our data
Taroko National Park is the only park on Wallace's Line with enough records to rate Macrobrochis gigas sightings: about 40% of wildlife watchers there report one on a given day.
Same family: Erebidae
The closest relatives of the Macrobrochis gigas that you can see in Taroko National Park (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Cocoa Tussock Moth (about 60%), Taiwan Yellow Tussock Moth (about 50%) and Chrysaeglia magnifica (about 40%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Macrobrochis gigas is recorded against all the insects logged in Taroko National Park (165 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.
