The Blue Tiger, Tirumala limniace is a common butterfly which I was able to photograph while visiting the Adyar Poonga. It belongs to the Danaid group (commonly known as crows and tigers) of the Brush-footed butterfly family, Nymphalidae. This butterfly shows gregarious migratory behaviour in southern India. The migratory populations have been observed mostly to consist of males.
It is a medium-sized butterfly with both wings having bluish-white semihyaline spots and streaks on a black background.
