Amata passalis
In 3 days ~60% in a week ~90%
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 30% of wildlife watchers report a Sandalwood Defoliator sighting in Jamshedpur on a given day, based on 7 verified sightings from GBIF citizen-science data. It is the 38th most-seen of the 47 insects we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
March and May
In those months about 40% of wildlife watchers report a Sandalwood Defoliator in Jamshedpur on a given day, against under 5% in June–July and October–November, the lowest months. Those are among Jamshedpur's driest months, with about 65 mm of rain a month against 360 mm in July.
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.
12th of 23
Of the 23 cities where we can rate Sandalwood Defoliator sightings, Jamshedpur ranks 12th at about 30%. The best odds are in Thiruvananthapuram (India, about 40%), Coimbatore (India, about 40%) and Prayagraj (India, about 40%).
Same family: Erebidae
The closest relatives of the Sandalwood Defoliator that you can see in Jamshedpur (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Tropical Tiger Moth (about 50%), Dot-Underwing Moth (about 40%) and Sugarcane Looper (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Sandalwood Defoliator is recorded against all the insects logged in Jamshedpur (7 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.
