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 some places, it may be found in congregations with Danaus genutia, Tirumala septentrionis, Euploea sylvester, Euploea core, Parantica aglea, and at high elevations, with Parantica nilgiriensis, on Crotalaria. Description Tirumala limniace is a large butterfly with wide wings. It has a wingspan of 90 to 100 millimeters, with the males being smaller than the females. The upper side of the wing is dark brown to black and patterned with bluish-white, semi-transparent spots and lines. The blue of the bluish-white spots consists of the pigment pterobilin. 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. In cell 1b of the forewing, which, like all the others, is an area on the wing bounded by veins, run two strips, sometimes connected, after which there is a large spot. A stripe runs from the base of the discoid cell, followed by a large spot that is notched from the wing tip (apex). A large oval spot sits at the base of cell 2, a significantly smaller spot is at the base of cell 3, followed by a small spot. Five short stripes can be seen in the post-disk region on the leading edge, only two of which are clearly defined. Two rows of irregular points run submarginally, the inner ones being larger than the outer ones. There is a stripe in cell 1a on the hind wing. A strip that divides from the base also runs through cells 1b and 1c. In the discoid cell there is a wide dividing strip. The lower branch hooks or has a short spur-like base. At the base of cells 2 and 3 there is a thin, V-shaped arch. In cells 2 and 5 there is a strong, wide stripe at the base. Two rows of scattered, irregular points also run submarginally, the inner ones being
