Physical Description of Adult Butterfly:
Above, the forewings are black with a white subapical band beyond the cell; the basal area is orange-red for the male (with the red confined to the base of the wings) and black for the female (with a yellowish-white patch in mid space 1b). The hindwing is entirely orange-red (paler in the female) except for the scalloped black distal border. Underneath, the wings are orange-red with white fasciae and adorned with black spots. The forewing cell has several black-edged, pale blue transverse stripes. The wing borders are dark coloured and deeply indented with lace-like pattern of white markings. One distinguishing feature to separate Malay Lacewing from other Cethosia species is the absence of a white submarginal band on the hindwing underside.

Field Observations of Butterfly Behaviour:
The Malay Lacewing is essentially a forest dweller and its local occurrence is confined within the sanctuary of the nature reserves in the catchment areas. It is not uncommon in the reserves, and adults can be spotted visiting flowers of flowering plants such as Leea indica in forest clearings or alongside forest trails. At times, females can also be seen checking out leaves of various plants in search of an ovipositing site.
