Delias eucharis, the common Jezebel, is a medium-sized pierid butterfly found in many areas of south and southeast Asia, especially in the non-arid regions of India, Bangladesh, Sri Lanka, Indonesia, Myanmar and Thailand. The common Jezebel is one of the most common of the approximately 225 described species in the genus Delias.
The wingspan of both males and females ranges from 6.5 to 8.5 cm. Upperside is white. The forewings have the veins broadly black, this colour broadened triangularly at the termination of the veins, costal margin narrowly black; a broad black postdiscal transverse band from costa to dorsum sloped obliquely outwards from costa to vein 4, thence parallel to termen. Hindwing with the veins similar but for three-fourths of their length much more narrowly black; a postdiscal transverse black band as on the forewing but much narrower, curved and extended only between veins 2 and 6; beyond this the veins are more broadly black and this colour as on the forewing broadens out triangularly at the termination of the veins; the interspaces beyond the postdiscal black band pink, due to the vermilion colouration of the underside showing through...

Possible
About 20% of wildlife watchers report a Common Jezebel sighting in Kolkata on a given day, based on 68 verified sightings from GBIF citizen-science data. It is the 30th most-seen of the 213 insects we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
November and December
In those months about 40% of wildlife watchers report a Common Jezebel in Kolkata on a given day, against about 10% in February–March, May–June and August, the lowest months. Those are among Kolkata's driest months, with about 15 mm of rain a month against 330 mm in July.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Common Jezebel sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
10th of 22
Of the 22 cities where we can rate Common Jezebel sightings, Kolkata ranks 10th at about 20%. The best odds are in Hyderabad (India, about 40%), Kalyan-Dombivli (India, about 30%) and Surat (India, about 30%).
Same family: Pieridae
The closest relatives of the Common Jezebel that you can see in Kolkata (family Pieridae, Whites, Yellows, and Sulphurs) are Psyche (about 20%), Western Striped Albatross (about 20%) and Common Grass Yellow (about 20%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Jezebel is recorded against all the insects logged in Kolkata (68 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.
