Adults are on wing from September to April, with peaks in October and February.

[6] Chinitinous spicules are present at the distal end of tibia in a f-f-a configuration, with a well-developed spur at the lower extremities.

A. pierus feature long palpi, a robust thorax, and a mesofur almost twice the length of tibia.

The uncus is in the form of a narrow strip, overlaying the large tegumen, with its distal edge slightly convex when flattened, while the subunci are short and exhibit bulging at their bases.

[5] The Dorsal Nectary Organ (DNO) develops in larvae later stages, mostly the third and subsequent instars.
