Bibasis sena, commonly known as the orange-tailed awlet, is a butterfly belonging to the family Hesperiidae, the skippers. It is also sometimes called the pale green awlet though that name can also refer to Burara gomata.
This skipper is found in Sri Lanka, India, China (Hainan), Myanmar, Cambodia, Thailand, Laos, Vietnam, Malaysia (Malay peninsula), Indonesian archipelago (including Borneo, Java, Kangean, Bali, Lombok, Bawean, Sumba, Sumbawa) and the Philippines.
