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.
In India, this skipper is found in the Western Ghats including the Nilgiris, Kodagu, Kanara, and the Himalayas, from Shimla eastward to Northeast India and onto Myanmar (recorded in the Karens and Dawnas). Also found in Andaman and Nicobar Islands.
The type locality for this species is the region of Bengal. William Harry Evans (1932) records the orange-tail awl as rare in India and very rare in the Andaman islands. He records the butterfly as not rare in south Myanmar, the Malay Peninsula and parts of the Indonesian archipelago.
Both sexes: The butterfly has a wingspan of 45 to 50 mm. Above, both sexes are an unblemished dark brown. The hindwings have an orange fringe. The... Wikipedia →

Rare
Under 5% of wildlife watchers report an Orangetail Awlet sighting in Singapore on a given day, based on 18 verified sightings from GBIF citizen-science data. It is the 576th most-seen of the 1045 insects we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
April
In that month about 10% of wildlife watchers report an Orangetail Awlet in Singapore on a given day, against under 5% in May to March, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Orangetail Awlet sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Singapore, in our data
Singapore is the only city on Wallace's Line with enough records to rate Orangetail Awlet sightings: under 5% of wildlife watchers there report one on a given day.
Same genus: Bibasis
The closest relatives of the Orangetail Awlet that you can see in Singapore (genus Bibasis) are Great Orange Awlet (about 10%) and Orange Awlet (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Orangetail Awlet is recorded against all the insects logged in Singapore (18 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
