The Common Evening Brown is known to
feed on padi. However, the food plant is likely to be substituted with
another monocotyledon (possibly bamboo) here in Singapore, where padi is
not grown.
The upperside is dark brown with a
black subapical patch bearing two white spots and inwardly shaded with
orange brown. The very variable underside is buff or grey, with fine dark
brown striations. A submarginal row of yellow-ringed ocelli are usually
found in the typical example. The variations in the undersides seem to
be related to the wet and dry seasons in the region. The butterflies usually
fly at dawn and shortly before dusk and are not normally seen during the
day, except when disturbed. 
This specimen was photographed feeding
on the flower of the Torch Ginger. It is a medium-sized butterfly, often attaining a
wingspan of 40 mm in most specimens. |
