The Dark Blue Tiger butterfly is found primarily in the Himalayas and Southern India. It migrates to avoid typhoons. Caterpillars feed on stapf, which has blooms eerily shaped like the background plant in my painting. The Dark Blue Tiger has spot that can range from blue to white on a brownish-black to black field. Obviously, the white on brown one that I photographed seems odd to be called a "blue" butterfly, but that's how it goes sometimes!
This butterfly is a female. I know this because males have visible scent glands on the hind wing, which this butterfly lacks. These butterflies are toxic to birds and lizards. In large quantity, they can cause heart attacks!
