About Arhopala eumolphus (Cramer, 1782)
Arhopala eumolphus (Cramer, 1782) can be recognized by the bright green lustre exhibited by males. It is still undetermined whether some of these green forms differ enough from one another to be classified as separate species. Typical specimens are from Northern India, and they are observed during the rainy season. Males of the species have abundant emerald-green coloration with a golden lustre, and their jet-black marginal band is narrow on the forewing and broad on the hindwing. Females, by contrast, are dark-red brown on the upper wing surface, with a violet-blue reflection in the basal portion, and the hindwing has a small tail. For the subspecies tagore Fruhst. from Assam, males are smaller but have a broader black marginal band than specimens from Sikkim. In females of this form, the blue color on the upper wing surface is darker, but extends further across the wing. This butterfly is mostly found in India, where its range extends from West Bengal and Sikkim to Arunachal Pradesh. It is also present in Nepal, Bhutan, Bangladesh, Myanmar, Hainan, Southeast Asia, Sumatra, Java, and Palawan.
