In 3 days ~20% in a week ~40%
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 Taichung on a given day, based on 8 verified sightings from GBIF citizen-science data. It is the 129th most-seen of the 197 insects we can rate there. Over three days the chance rises to about 20%, and over a week to about 40%, if each day is a fresh chance.
June
In that month about 20% of wildlife watchers report a Macrobrochis gigas in Taichung on a given day, against under 5% in August to March, the lowest months. That is one of Taichung's wettest months, with about 310 mm of rain against 40 mm in December.
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, Taichung ranks 3rd at about 10%, level with the leaders once rounded. The best odds are in Dehradun (India, about 10%) and Taipei (Taiwan, about 10%).
Same family: Erebidae
The closest relatives of the Macrobrochis gigas that you can see in Taichung (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Cocoa Tussock Moth (about 20%), Brown Tussock Moth (about 10%) and Taiwan Yellow Tussock Moth (about 10%), 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 Taichung (8 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.
