Hasora badra, the common awl, is a butterfly belonging to the family Hesperiidae, which is found in Southeast Asia. The butterfly, which has a wingspan of 50 to 55 mm, is unmarked dark brown above. It resembles the common banded awl (Hasora chromus), except that it has no white band below; and the apex of the forewing and the disc of the hindwing below are purple washed. The male has apical spots but no brands above. The female has large yellow spots in cell 2 and 3, and apical dots.
The Sri Lankan race has no apical spots on the male above and no purple wash below. Edward Yerbury Watson (1891) gives a detailed description, shown below: Male and female yellowish brown. Male, with a suffused blackish subbasal patch; forewing with three conjugated very small yellowish semitransparent spots near the costa, one fourth from the apex. Cilia pale greyish brown. Underside brown suffused with purple; forewing with a blackish costal patch before the apex, posterior margin yellowish; hindwing with a subbasal and submarginal suffused blackish band, the latter terminating in a black patch on anal lobe; above the patch is a purple-white streak, and within...

Rare
Under 5% of wildlife watchers report a Common Awl sighting in Hong Kong on a given day, based on 9 verified sightings from GBIF citizen-science data. It is the 778th 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.
December
In that month about 10% of wildlife watchers report a Common Awl in Hong Kong on a given day, against under 5% in January to November, the lowest months. That is one of Hong Kong's driest months, with about 25 mm of rain against 280 mm in June.
Between 5 and 8 am
Across all the parks we cover, that three-hour window holds the most Common Awl sightings with a recorded time, and about 6 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
7th of 8
Of the 8 cities where we can rate Common Awl sightings, Hong Kong ranks 7th at under 5%. The best odds are in Kochi (India, about 20%), Mumbai (India, about 20%) and Ponnani (India, about 20%).
GBIF citizen-science records
It is estimated from how often the Common Awl is recorded against all the insects logged in Hong Kong (9 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.
