Adult
 
The Coeliadinae comprises of large robust skippers which fly mainly at dawn and dusk, and which are generally dark in colour but often have a bluish sheen on the upperside wings. They have a swift and powerful flight but generally only cover very short distances on each foray; and rest frequently on the under surface of leaves on trees or bushes.
 
The Common Awl Hasora badra is dark brown on the upper surface, and devoid of markings in the male. The forewings of the female however have 3 large yellowish hyaline spots in the median area, and 3 small pale spots on the subapical area. On the underside both sexes are dark, with a purplish sheen, and a small white spot on the discal cell.
