It has jagged outer margins on both wings. The forewing apex is more falcate in dry season individuals. The upper surface is black with a shiny greenish blue tint on the base. The brilliant blue band seen in the distal area is larger in females. There is a diffused blue spot at the upper margin beyond this band and a distal row of diffused spots on the hindwing. The underside is marked in shades of brown, black and grey giving it the ability to camouflage itself among leaf litter.
The Blue Admiral never feeds on flowers and entirely depends on overripe fruits and tree sap. It flies quickly and very low in open spaces especially along waterways and goes up in forests for food and to lay eggs. It basks with fully opened wings in the morning. Afterwards, it settles with closed wings on the ground or on tree trunks with mosses and lichens. Males use the ‘wait and see method’ to find their mates.
Habitats and Distribution
This butterfly can be found in both the wet and intermediate zones, but only appears in high numbers from the lower hills to the highest mountains. It is a forest-loving species, but also visits adjacent streams in grasslands such as in Horton Plains.
Larval Food Plants
Smilax perfoliata, S. zeylanica. It probably also feeds on S. aspera in the hills
