Cyrestis thyodamas, the common map, is a species of butterfly in the family Nymphalidae. It was first described by Jean Baptiste Boisduval in 1836. It is found in the Indian subcontinent and Southeast Asia. Males and females upperside white, in many specimens pale ochraceous yellow, veins black. Forewing with four very slender irregularly sinuous transverse black lines, the costal margin shaded with ochraceous at base and fuscous beyond; cell crossed by three or four additional short lines; a postdiscal very incomplete series of white-centred broad fuscous rings in the interspaces, tinged with ochraceous near the tornus and broadly interrupted in interspaces 3 and 4; beyond this two transverse black lines not reaching the dorsal margin, shaded with fuscous between; the apex broadly and the termen also shaded with fuscous. Hindwing with three transverse fine lines; a pair of postdiscal broad black lines shaded with light sepia brown between, forming a conspicuous band, the outer line broken and incomplete, followed by two irregular black lines, a subterminal more pronounced black line, and posteriorly a narrow black terminal margin; dorsal margin broadly fuscous at...

Possible
About 20% of wildlife watchers report a Common Mapwing sighting in Dehradun on a given day, based on 10 verified sightings from GBIF citizen-science data. It is the 26th most-seen of the 73 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.
January and July
In those months about 40% of wildlife watchers report a Common Mapwing in Dehradun on a given day, against under 5% in February–March, June and September–December, the lowest months. Those are among Dehradun's wettest months, with about 200 mm of rain a month against 5 mm in November.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Common Mapwing sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
4th of 12
Of the 12 cities where we can rate Common Mapwing sightings, Dehradun ranks 4th at about 20%. The best odds are in Naha (Japan, about 40%), Taipei (Taiwan, about 20%) and Tuen Mun (China, about 20%).
Same family: Nymphalidae
The closest relatives of the Common Mapwing that you can see in Dehradun (family Nymphalidae, Brush-footed Butterflies) are Tawny Coster (about 40%), Lemon Pansy (about 30%) and Plain Tiger Butterfly (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Mapwing is recorded against all the insects logged in Dehradun (10 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.
