The Blue Tiger (Tirumala limniace) is a butterfly found in India that belongs to the Crows and Tigers, that is, the Danaid group of the Brush-footed butterflies family. This butterfly shows gregarious migratory behaviour in southern India. Closely resembles Tirumala limniace, Cramer, but is always sufficiently distinct to be easily recognized, even on the wing. From T. limniace it differs on the upperside in the ground-colour being darker and the semihyaline markings narrower, more distinct, and of a bluer tint, In the fore wing, in interspace 1 the two streaks are narrower, never coalescent, the upper one forming an oval detached spot; the short streaks above vein 5 are outwardly never truncate, always acute. In the hind wing the two streaks if the discoidal cell united at base are wide apart at their apices, the lower one never formed into a hook. On the underside this species is generally darker, the apex of the fore wing and the whole of the ground-colour of the hind wing not being of the conspicuous golden brown that they are in Tirumala limniace. The Himalayas from Simla to Sikhim, into Assam, Myanmar and Southeast Asia; Orissa, West.Bengal, Southern India, the Western Ghats and Nilgiris; Sri Lanka.
This series of photos was taken on my second visit to the Butterfly Pavilion in Denver, Colorado. Couldn't resist going again! This species is one of the predominant species (78%) during the migratory season in southern India during which many species migrate. Both males and females appear to migrate in equal numbers
