The Dark Blue Tiger (Tirumala septentrionis) is a Danaid butterfly found in South and Southeast Asia.
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.Expanse: 80115 mm.

Distribution

The Himalayas from Simla to Sikhim, into Assam, Myanmar and Southeast Asia; Orissa ;W.B, Southern India., the Western Ghats and Nilgiris; Sri Lanka.

Habits

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.

Life cycle

Caterpillar is similar to that of T. limniace (see Jour. Bomb. N. H. Soc. x, 1896, p. 240). It is said by MacKinnon and de Niceville to feed on Vallaris dichotoma (Jour. Bomb. N. H. Soc. xi, 1807, p. 212). Other species include Cosmostigma racemosa, Heterostemma brownii and Cocculus spp.
