Eudocima materna, the dot-underwing moth, is a moth of the family Erebidae found in widespread parts of the world, mainly in tropical Asia extending to New Guinea and Australia as well as in Africa. Reports from the United States, Canada and the French Antilles are now considered to be Eudocima apta. The species can be differentiated from other Eudocima moths by the presence of small central black dot in each hindwing. The species was first described by Carl Linnaeus in his 1767 12th edition of Systema Naturae.

A silvery patch found on vein 1 and another below lower angle of cell. A marginal black band with crenulate inner edge. There is a series of white cilia spots. Ventral side is orange. Forewings with costa and apical area blotched with rufous. Oblique postmedial and sub-apical black... Wikipedia →

With luck
About 10% of wildlife watchers report a Dot-Underwing Moth sighting in Kolkata on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 101st most-seen of the 213 insects we can rate there. Over three days the chance rises to about 30%, and over a week to about 50%, if each day is a fresh chance.
December
In that month about 20% of wildlife watchers report a Dot-Underwing Moth in Kolkata on a given day, against under 5% in January, March, May and October, the lowest months. That is one of Kolkata's driest months, with about 10 mm of rain against 330 mm in July.
Between 8 and 11 pm
Across all the parks we cover, that three-hour window holds the most Dot-Underwing Moth sightings with a recorded time, and about 8 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
18th of 24
Of the 24 cities where we can rate Dot-Underwing Moth sightings, Kolkata ranks 18th at about 10%. The best odds are in Jamshedpur (India, about 40%), Coimbatore (India, about 20%) and Nagpur (India, about 20%).
Same family: Erebidae
The closest relatives of the Dot-Underwing Moth that you can see in Kolkata (family Erebidae, Underwing, Tiger, Tussock, and Allied Moths) are Seven-Spotted Handmaiden Moth (about 30%), Tropical Tiger Moth (about 20%) and Banyan Tussock Moth (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dot-Underwing Moth is recorded against all the insects logged in Kolkata (16 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.
