Amata passalis
In 3 days ~50% in a week ~80%
Amata passalis, the sandalwood defoliator, is a moth of the family Erebidae first described by Johan Christian Fabricius in 1781. It is found in Sri Lanka and India. The average life cycle of the species in captivity is 62 days. After mating, the adult female lays about 305 eggs in a lifespan of 3.87 days. It is known to breed all year around and passes through 6-11 generations a year. There are eight larval instars. First and last instar larvae are about 1.97 mm and 29.29 mm in length, respectively. Adults usually emerge within 1 to 2 hours of sunrise. After a day, they are ready for mating.
It is known mainly as a defoliator of sandalwood (Santalum album) in India. It is also recorded on various alternate food plants, mainly cowpeas, various other pulses, and ornamental plants. The larval stage of Apanteles nepitae can be used as a parasite to control the moth.

Possible
About 20% of wildlife watchers report a Sandalwood Defoliator sighting in Nagpur on a given day, based on 5 verified sightings from GBIF citizen-science data. It is the 10th most-seen of the 17 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
March, August and October
In those months about 40% of wildlife watchers report a Sandalwood Defoliator in Nagpur on a given day, against under 5% in January–February, April–July, September and November, the lowest months.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Sandalwood Defoliator sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
17th of 23
Of the 23 cities where we can rate Sandalwood Defoliator sightings, Nagpur ranks 17th at about 20%. The best odds are in Thiruvananthapuram (India, about 40%), Coimbatore (India, about 40%) and Prayagraj (India, about 40%).
GBIF citizen-science records
It is estimated from how often the Sandalwood Defoliator is recorded against all the insects logged in Nagpur (5 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.
