Chocolate Demon is a relatively large skipper. On the upperside, the wings are dark brown and unmarked. On the underside, the wings are brown with marginal areas of both wings paler than the ground colour. The proboscis is particularly long compared to other skipper species.
Field Observations of Butterfly Behaviour:
Chocolate Demon is moderately common in Singapore. The adults are typically found in parks, park connectors and gardens where one of its host plants in the Zingiberaceae is cultivated. The adults fly in an erratic and hopping manner amongst low shrubbery. They visit flowers for nectar, and puddle on birding droppings and other animal excretions.
