Hyblaea puera
In 3 days ~30% in a week ~60%
Hyblaea puera, the teak defoliator, is a moth and cryptic species complex native to South Asia and Southeast Asia, though also reported from Central America and Africa. It was first described by Pieter Cramer in 1777. The caterpillar feeds on teak and other trees, and considered to be one of the major teak pests around the world.
Hyblaea puera occurs in forests across southern Asia from India, Sri Lanka and Bangladesh, and southeast Asia from Thailand to New Guinea, and north Queensland in Australia. The species has been reported from Guadeloupe, and Suriname.
The adult moths are comparatively small, with a wingspan of 3–4 cm (1.2–1.6 in), and have a characteristic resting posture that conceals the black and orange-yellow hindwings under the greyish-brown forewings. There are five larval instars, with the last instar measuring about 3.5–4.5 cm (1.4–1.8 in), and there is considerable colour variation in the fourth and fifth instars; the body may be either wholly black or dark greyish to black, with longitudinal coloured bands which may include a dorsal orange or ocherous band and lateral white lines.

With luck
About 10% of wildlife watchers report a Teak Defoliator sighting in Ahmedabad on a given day, based on 11 verified sightings from GBIF citizen-science data. It is the 38th most-seen of the 52 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Teak Defoliator in Ahmedabad on a given day, against under 5% in September to June, the lowest months. That is one of Ahmedabad's wettest months, with about 270 mm of rain against almost none in January.
Between 9 pm and midnight
Across all the parks we cover, that three-hour window holds the most Teak Defoliator sightings with a recorded time, and about 9 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
Yes
Of the 9 cities where we can rate Teak Defoliator sightings, Ahmedabad has the highest daily chance: about 10%. Next come Yogyakarta (Indonesia, about 10%) and Mumbai (India, about 10%).
Same order: Lepidoptera
The closest relatives of the Teak Defoliator that you can see in Ahmedabad (order Lepidoptera, Butterflies and Moths) are Hawaiian Beet Webworm Moth (about 30%), Indian Lily Moth (about 20%) and Common Jay (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Teak Defoliator is recorded against all the insects logged in Ahmedabad (11 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.
