Dakhan Common Acacia Blue (Surendra quercetorum biplagiata)

This is the butterfly of Lycaenids or Blues family because the upperwings of male Acacia Blue has blue colour [ifoundbutterflies]. Female was seen in Soneri-bag area of lake side in IITB campus. Swapnil and I observed female laying eggs on some Acacia spp. plant. This was first time we have seen this butterfly in the campus. Female was often seen around noon near its larval host plant. This plant is shared by Common Nawab also. Female laid an egg on thorn of this plant.
Its caterpillar has friendly association with ants. Ants constantly protect caterpillar againts parasites attacks. In return caterpillar secretes sweet liquid- honey dew, for ants!!
