About Hasora vitta (Butler, 1870)
This butterfly species Hasora vitta has a wingspan ranging from 45 to 55 mm, and its upper wing surfaces are dark brown. It closely resembles the related species Hasora chromus, the common banded awl, but differs by having a broad, outwardly diffused white band on the underside of its hindwing, and its wings have more prominent gloss. Additional distinguishing features separate males and females of the species. For male Hasora vitta, the upper side of the forewing has an apical spot, and sometimes an extra spot in cell 3. Males do not have a brand on the upper forewing. For female Hasora vitta, the apical spot on the forewing is larger than that of the male, and an extra spot is present in cell 2. Hasora vitta, commonly called the plain banded awl, ranges across South and East Asia. In India, it is found in southern Kanara, Sikkim, and Assam, and its distribution extends eastward to Myanmar, Thailand, western China, Malaysia, Indonesia, and the Philippines.
