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 Taipei on a given day, based on 16 verified sightings from GBIF citizen-science data. It is the 422nd most-seen of the 765 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.
July and August
In those months about 10% of wildlife watchers report a Common Awl in Taipei on a given day, against under 5% in September to June, the lowest months.
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.
6th of 8
Of the 8 cities where we can rate Common Awl sightings, Taipei ranks 6th 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 Taipei (16 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.
