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.

Rare
Under 5% of wildlife watchers report a Banyan Tussock Moth sighting in Singapore on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 788th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
Any time of year
In every month with enough records, under 5% of wildlife watchers report a Banyan Tussock Moth in Singapore on a given day, so our monthly data shows no clear season.
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.
20th of 20
Of the 20 cities where we can rate Banyan Tussock Moth sightings, Singapore ranks 20th at under 5%. The best odds are in Taipei (Taiwan, about 20%), Hong Kong (China, about 20%) and Tuen Mun (China, about 10%).
GBIF citizen-science records
It is estimated from how often the Banyan Tussock Moth is recorded against all the insects logged in Singapore (9 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.
