Arhopala eumolphus

A.eumolphus is recognisable by the males showing above a bright green lustre; but it has not been decided whether some of these green forms do not differ so much from each other as to be dealt with as separate species. — Typical specimens are from Northern India, from the rainy season. Male abundantly emerald-green with a golden lustre, the jet-black marginal band being narrow on the forewing and broad on the hindwing. Female above dark red-brown with a violettish-blue reflection in the basal portion; hindwing with 1 small tail. In tagore Fruhst., from Assam, the male is smaller, but it has a broader black marginal band than specimens from Sikkim. In the female of this form the blue colour above is darker, but it extends farther across the wing. —[1]

The butterfly is mostly seen in India, ranging from West Bengal and Sikkim to Arunachal Pradesh, and is also found in Nepal, Bhutan, Bangladesh, and Myanmar.[2] Hainan, Southeast Asia, Sumatra, Java, Palawan.
