Euploea core, also known as the common crow, is a common butterfly found in South Asia to Australia. In India it is also sometimes referred to as the common Indian crow, and in Australia as the Australian crow. It belongs to the crows and tigers subfamily Danainae (tribe Danaini).
E. core is a glossy-black, medium-sized 85–95 mm (3.3–3.7 in) butterfly with rows of white spots on the margins of its wings. E. core is a slow, steady flier. Due to its unpalatability it is usually observed gliding through the air with a minimum of effort. As caterpillars, this species sequesters toxins from its food plant which are passed on from larva to pupa to the adult. While feeding, it is a very bold butterfly, taking a long time at each bunch of flowers. It can also be found mud-puddling with others of its species and often in mixed groups. The males of this species visit plants like Crotalaria and Heliotropium to replenish pheromone stocks which are used to attract a female during courtship.
The common crow is the most common representative of its genus, Euploea. Like the tigers (genus Danaus), the crows are inedible and thus mimicked by other Indian butterflies (see Batesian mimicry). In addition, the Indian species of the genus Euploea show another kind of mimicry, Müllerian mimicry. Accordingly, this species has been studied in greater detail than other members of its genus in India. Wikipedia →

Possible
About 20% of wildlife watchers report a Common Crow sighting in Jim Corbett National Park on a given day, based on 5 verified sightings from GBIF citizen-science data from 2019 to 2026. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
March, July and October–November
In those months about 30% of wildlife watchers report a Common Crow in Jim Corbett National Park on a given day, against under 5% in May–June, September and December–February, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Common Crow sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 11
Of the 11 parks where we can rate Common Crow sightings, Jim Corbett National Park ranks 10th at about 20%. The best odds are in Udawalawe National Park (Sri Lanka, about 40%), Minneriya National Park (Sri Lanka, about 30%) and Kanha National Park (India, about 30%).
GBIF citizen-science records
It is estimated from how often the Common Crow is recorded against all the insects logged in Jim Corbett National Park (5 verified sightings from 2019 to 2026), 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.
