Physical Description of Adult Butterfly:

There is usually a small white hyaline spot in space 4 of the forewing. The hindwing is unmarked. Underneath, the wings are brown and dusted with purplish scales next to the termens. The purplish hue is more readily observed in pristine specimens. The antenna has a pale whitish band just below the club.
Field Observations of Butterfly Behaviour:
Banded Demon is moderately common in Singapore. The adults are rather localized and are typically found in the vicinity of its host plant in the fringe of the nature reserve. The adults are fast fliers among the ground cover and shrubbery. They visit flowers for nectar, and at times perch on sun-bathing spots with half-open wings.
