Herona marathus, the pasha is a species of nymphalid butterfly found in India.
Description
The adults are dark brown above with two yellow or white discal bands on forewing and hindwing. They have a basal streak in vein 1b of forewing. Underside of forewing, in vein 5 with white streak in outer half till the termen.
Habits
It is fairly common up to 4000 ft (1200 m) in the Sikkim-Darjeeling area. Most frequent between 2000 and 3000 ft (600โ900 m). It is very fond of over-ripe fruits. Visits damp patches for puddling. According to Haribal (1992), when disturbed it sits with head down and wings close to tree trunks and thus perfectly camouflaged. Very difficult to catch/locate in this stage. Haribal (1992) saw it in Chungthang and Mangan area of Sikkim.
