Diaphania indica, the cucumber moth or cotton caterpillar, is a widespread but mainly Old World moth species. It belongs to the grass moth family, and therein to the large subfamily Spilomelinae. This moth occurs in many tropical and subtropical regions outside the Americas, though it is native to southern Asia; it is occasionally a significant pest of cucurbits and some other plants.
This species was originally described by William Wilson Saunders in 1851 under the misspelled name Eudioptes indica (properly:Eudioptis), using specimens from Java. His syntypes are in the Hope Entomological Collections of the Oxford University Museum of Natural History.
The wingspan is about 30 mm. Adults have translucent whitish wings with broad dark brown borders. The body is whitish below, and brown on top of head and thorax as well as the end of the abdomen. There is a tuft of light brown "hairs" on the tip of the abdomen, vestigial in the male but well developed in the female. It is formed by long scales which are carried in a pocket on each side of the 7th abdominal segment, from where they can be everted to form the tufts. Unfertilized females are often seen sitting around with... Wikipedia →

Possible
About 20% of wildlife watchers report a Cucumber Moth sighting in Kathmandu on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 39th most-seen of the 71 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.
July, September and November–December
In those months about 30% of wildlife watchers report a Cucumber Moth in Kathmandu on a given day, against under 5% in January–May, August and October, the lowest months.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Cucumber Moth sightings with a recorded time, and about 6 in 10 of them come between 6 pm and 6 am: it is seen both by day and at night.
3rd of 26
Of the 26 cities where we can rate Cucumber Moth sightings, Kathmandu ranks 3rd at about 20%. The best odds are in Jamshedpur (India, about 30%) and Vadodara (India, about 20%).
Same family: Crambidae
The closest relatives of the Cucumber Moth that you can see in Kathmandu (family Crambidae, Crambid Snout Moths) are Hawaiian Beet Webworm Moth (about 20%) and Mung Bean Moth (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Cucumber Moth is recorded against all the insects logged in Kathmandu (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.
