Hasora chromus, the common banded awl, is a butterfly belonging to the family Hesperiidae which is found in the Indian subcontinent, Southeast Asia and Australia. The common banded awl is found throughout the Indian subcontinent, Southeast Asia (including the Malay Peninsula and the Indonesian archipelago), South China, Okinawa, Japan, United Arab Emirates, Papua New Guinea and Australia.
It occurs in the plains and hills up to 7,000 feet (2,100 m). It is found in jungle and open country in areas of light and heavy rainfall. Both sexes: Wingspan 45–50 mm. The male and female are dark vinaceous (colour of red wine) brown. The cilia is greyish brown while the head and thorax are greenish brown. The abdomen, third joint of palpi and the legs are also brown; the palpi and thorax beneath are dull yellow.
Below, the hindwing is dark brown with more of less of dull blue-greyish gloss. It has a narrow discal band, whitish in colour which is diffused on the outside margin. It has a black tornal patch. This black spot is clearly visible only at the time of hatching for a few moments but is becomes hidden in the fold of the hindwing, a characteristic of this genus... Wikipedia →

Rare
Under 5% of wildlife watchers report a Common Banded Awl sighting in Hong Kong on a given day, based on 14 verified sightings from GBIF citizen-science data. It is the 583rd most-seen of the 1125 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 and June
In those months about 10% of wildlife watchers report a Common Banded Awl in Hong Kong on a given day, against under 5% in May and July–March, the lowest months. Those are among Hong Kong's wettest months, with about 190 mm of rain a month against 25 mm in December.
15th of 17
Of the 17 cities where we can rate Common Banded Awl sightings, Hong Kong ranks 15th at under 5%. The best odds are in Salem (India, about 30%), Jabalpur (India, about 20%) and Raipur (India, about 20%).
GBIF citizen-science records
It is estimated from how often the Common Banded Awl is recorded against all the insects logged in Hong Kong (14 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.
