Description
For a key to the terms used, see Glossary of entomology terms.

The butterfly, which has a wingspan of 45 to 55 mm, is dark brown above. It resembles the common banded awl (Hasora chromus), except in the case of having a broad white band on the under hindwing which is outwardly diffused; also, its wings are more prominently glossed.[6][7]

Other differentiating characteristics are:

Male: The upper forewing has an apical spot, sometimes with another in 3. The upper forewing has no brand.[6]

Female: The apical spot in the case of the female is larger, and there is an additional spot in 2.[6]

Taxonomy

The butterfly has two subspecies:

Range

The plain banded awl is found in India in the south (Kanara), Sikkim, Assam[2] and eastwards to Myanmar, Thailand, western China, Malaysia, Indonesia and the Philippines.[4][8]

Status

Not rare as per Evans (1932).[8] Not common as per Wynter-Blyth (1957).[6]

Host-plants

The caterpillars have been recorded on Derris spp., Pongamia spp,Millettia extensa, Endosamara racemosa, Millettia glabra and Spatholobus ferrugineus.[4][9]

gollark: If you set `shell.allow_disk_startup` to `false` (it's per computer, programs can do that) they will *not* boot off disks.
gollark: No, it is *not* vulnerable to booting from disks, there's a setting.
gollark: I mean, except somehow exploiting bugs in CC to gain arbitrary code execution on the server.
gollark: There is no way around these things.
gollark: PotatOS can't stop you from putting it in a disk drive and deleting it, or from editing the files in `world`, or from adjusting the CC config so it doesn't work.
