Perina nuda, the clearwing tussock moth or banyan tussock moth, is a moth of the family Erebidae. The species was first described by Johan Christian Fabricius in 1787. It is found in the Indian subregion, Sri Lanka, southern China, Hong Kong, Thailand and Sundaland.
Adults show striking sexual dimorphism. The caterpillar has a greyish head and flanks, with the broad black dorsum. Its setae are white. The pupa is bristly, piebald in dark grey and cream. The setae on each pupa is orange. The caterpillar is a minor pest on several banyan species such as Ficus benjamina, Ficus benghalensis, Ficus racemosa, Ficus pumila and Ficus religiosa, and also many crop plants like Artocarpus and Mangifera.
The species is associated with an RNA virus called Perina nuda virus. Semiochemicals of Perina nuda, the Clearwing tussock moth. The Pherobase.

Possible
About 20% of wildlife watchers report a Banyan Tussock Moth sighting in Hong Kong on a given day, based on 210 verified sightings from GBIF citizen-science data. It is the 48th most-seen of the 1125 insects we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
January–April and November
In those months about 20% of wildlife watchers report a Banyan Tussock Moth in Hong Kong on a given day, against about 10% in May–October and December, the lowest months. Those are among Hong Kong's driest months, with about 55 mm of rain a month against 280 mm in June.
Between 1 and 4 pm
Across all the parks we cover, that three-hour window holds the most Banyan Tussock Moth sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is seen both by day and at night.
Among the best
Of the 20 cities where we can rate Banyan Tussock Moth sightings, Hong Kong ranks 2nd at about 20%, level with the leaders once rounded. The best odds are in Taipei (Taiwan, about 20%).
Same family: Erebidae
The closest relatives of the Banyan Tussock Moth that you can see in Hong Kong (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Orvasca subnotata (about 20%), Zhejiang Tussock Moth (about 10%) and Cocoa Tussock Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Banyan Tussock Moth is recorded against all the insects logged in Hong Kong (210 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.
