Description
The history of V. cardui is Malaya is of considerable interest. Until recently, the only Malayan records referred to a specimen found on Penang Hill in 1886, and a second example attributed to Singapore Island.

Habitat & Habits
The butterfly has a habit of returning repeatedly to the same spot when disturbed, but is is not easily caught. The larva is black with yellowish spines and markings. It feeds chiefly on Carduus (Thistle) in Europe, but Artemisia and Blumea (both Compositae) are among the host plants in the Oriental Region. (pg 161 - C&P4).
