Forewing with greyish-black costal edge, a broad longitudinal band from base of the costa and filling up the cell — with the exception of a thin streak above the median vein, this black cell-band more or less thinly extends along the upper median veinlet and joins a broad outer-marginal decreasing band extending sinuously from before the apex to posterior angle, enclosing the white sub-apical oblique quadrate patch, the outer band showing faint...

Possible
About 20% of wildlife watchers report a Western Striped Albatross sighting in Kolkata on a given day, based on 63 verified sightings from GBIF citizen-science data. It is the 38th 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.
April, July and November–December
In those months about 30% of wildlife watchers report a Western Striped Albatross in Kolkata on a given day, against about 10% in January, June and August–October, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Western Striped Albatross sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
16th of 32
Of the 32 cities where we can rate Western Striped Albatross sightings, Kolkata ranks 16th at about 20%. The best odds are in Cần Thơ (Vietnam, about 50%), Yogyakarta (Indonesia, about 40%) and Davao City (Philippines, about 30%).
Same family: Pieridae
The closest relatives of the Western Striped Albatross that you can see in Kolkata (family Pieridae, Whites, Yellows, and Sulphurs) are Common Jezebel (about 20%), Psyche (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 Western Striped Albatross is recorded against all the insects logged in Kolkata (63 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.
