In 3 days ~30% in a week ~50%
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.

With luck
About 10% of wildlife watchers report a Macrobrochis gigas sighting in Taipei on a given day, based on 134 verified sightings from GBIF citizen-science data. It is the 89th most-seen of the 765 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.
May and June
In those months about 20% of wildlife watchers report a Macrobrochis gigas in Taipei on a given day, against under 5% in August to March, the lowest months. Those are among Taipei's wettest months, with about 250 mm of rain a month against 90 mm in February.
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.
Among the best
Of the 5 cities where we can rate Macrobrochis gigas sightings, Taipei ranks 2nd at about 10%, level with the leaders once rounded. The best odds are in Dehradun (India, about 10%).
Same family: Erebidae
The closest relatives of the Macrobrochis gigas that you can see in Taipei (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Asota heliconia (about 20%), Chrysaeglia magnifica (about 20%) and Banyan Tussock Moth (about 20%), 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 Taipei (134 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.
