The Blue Tiger[ Tirumala Limniace]

Chandana Witharanage posted a photo:

Tirumala limniace, the blue tiger is a butterfly found in South Asia and Southeast Asia that belongs to the crows and tigers, that is, the danaid group of the brush-footed butterfly family. This butterfly shows gregarious migratory behaviour in southern India.
In general, all butterflies can directly absorb heat from the sun via their wings to facilitate autonomous flight. Studies on blue tiger butterflies show that high-intensity light significantly increased flight activity. Blue tiger butterflies have a wing surface color that is composed of both light and dark colors. The dark areas on the wing surfaces are the heat absorption areas that allow for the facilitation of autonomous flight.
