Mycalesis mineus, the dark-brand bush brown, is a species of satyrine butterfly found in Asia. Wet-season form: Upperside dark Vandyke brown; forewings and hindwings with slender subterminal and terminal pale lines. Forewing with a single white-centred, fulvous-ringed, black ocellus, generally set in a square pale area, in interspace 2, occasionally a similar smaller ocellus without any pale surrounding area in interspace 5. Hindwing uniform sometimes with one or two obscure postmedian ocelli. Underside: ground colour similar; forewings and hindwings crossed by a transverse dusky-white discal band, well-defined inwardly, diffuse outwardly, followed by a postdiscal series of ocelli surrounded by a dusky-yellowish, sometimes purplish white, line; the ocelli are similar to the ocelli on the upperside, and vary from two to four on the forewing and from five to seven (the preapical two being sometimes obsolescent) on the hindwing; of these latter the posterior four, not three as in Mycalesis perseus, are in a straight line; finally, beyond the rows of ocelli on both wings there are pale or purplish-white subterminal and terminal sinuous lines.

With luck
About 10% of wildlife watchers report a Dark-Branded Bushbrown 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.
September
In that month about 30% of wildlife watchers report a Dark-Branded Bushbrown in Kolkata on a given day, against under 5% in December to June, the lowest months. That is one of Kolkata's wettest months, with about 260 mm of rain against 10 mm in December.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Dark-Branded Bushbrown sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
8th of 15
Of the 15 cities where we can rate Dark-Branded Bushbrown sightings, Kolkata ranks 8th at about 10%. The best odds are in Tuen Mun (China, about 30%), Hong Kong (China, about 20%) and Guwahati (India, about 20%).
Same family: Nymphalidae
The closest relatives of the Dark-Branded Bushbrown that you can see in Kolkata (family Nymphalidae, Brush-footed Butterflies) are Plain Tiger Butterfly (about 30%), Tawny Coster (about 30%) and Blue Tiger (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Dark-Branded Bushbrown 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.
