Tirumala limniace, the blue tiger, [1] [2] is a species of butterfly found in South Asia, and Southeast Asia [1] [2] that belongs to the brush-footed butterfly family, Nymphalidae. [3] More specifically it is part of the crows and tigers or danaid group. 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 .
Tirumala limniace is a small 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. [3] 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 larger than the outer ones.
The males differ from the females by a black pocket filled with scented scales in cell 1c, near the discoid cell on the upper side of the hind wings. The pockets are only created after hatching while the moth inflates its wings by turning up scented flakes. They play an important role in courtship, along with tufts of hair that can be turned out on the abdomen. The hairs sprout almost only from the rear third of the tuft of hair, a typical feature of the Danaini genera grouped under the clade Danaina.
The underside of the forewing is black, only the apex, like the underside of the hind wings, is olive-brown. The pattern largely corresponds to the top.
The antennae are black, as are the head and thorax, these two still bearing white dots and lines. The top of the abdomen is dark, the underside is pale brownish yellow colored with white shimmering underneath at the segment boundaries
The butterfly larvae generally feed on plants of family Asclepiadaceae. The recorded host plants are: [4]
Yellowish white; 3rd and 12th segments, each with a pair of fleshy filaments, black and greenish white; each of the segments with four transverse black bars, the second bar on all broader than the others, bifurcated laterally, a yellow longitudinal line on each side; head, feet and claspers spotted with black. [4] The larva is around 1.21 centimetres (0.48 in) in length and weighs around 5 milligrams (0.077 gr) initially, but grows double that size and four times that weight within 48 hours.
"Green with golden scattered spots and beaded dorsal crescent". (Frederic Moore quoted in Bingham) [4]
The species is distributed in South Asia and Southeast Asia. [1] [2] In 2019, a single adult specimen was reported from the Balearic Islands, marking it the first record of the species in Europe. [5]

This species migrates extensively during the monsoons in southern India. The migratory populations have been observed to consist nearly entirely of males. [6] It is also known to mud-puddle during migration. [7]
Acraea terpsicore, the tawny coster, is a small, 53–64 millimetres (2.1–2.5 in), leathery-winged butterfly common in grassland and scrub habitats. It belongs to the Nymphalidae or brush-footed butterfly family. It has a weak fluttery flight. It is avoided by most insect predators. This species and the yellow coster are the only two Indian representatives of the predominantly African tribe Acraeini. It is found in India, Sri Lanka, Indonesia, Maldives to Myanmar, Thailand, Laos, Cambodia, Vietnam, Bangladesh, Malaysia, Singapore, and recently Australia.
Euploea core, also known as the common crow, is a common butterfly found in South Asia to Australia. In India it is also sometimes referred to as the common Indian crow, and in Australia as the Australian crow. It belongs to the crows and tigers subfamily Danainae.
Euthalia aconthea, the common baron, often called simply baron, is a medium-sized nymphalid butterfly native to Sri Lanka, India and southeast Asia. It flies with stiff wing beats and often glides. The wing is not flapped very far below the horizontal.
Phalanta phalantha, the common leopard or spotted rustic, is a sun-loving butterfly of the nymphalid or brush-footed butterfly family.
Parantica aglea, commonly known as the glassy tiger, is a butterfly found in the Indomalayan realm. The species is a member of the Danainae subfamily of the Nymphalidae family.
Danaus genutia, the common tiger, is one of the common butterflies of India. It belongs to the "crows and tigers", that is, the Danainae group of the brush-footed butterflies family. The butterfly is also called striped tiger in India to differentiate it from the equally common plain tiger, Danaus chrysippus. The species was first described by Pieter Cramer in 1779.
Elymnias hypermnestra, the common palmfly, is a species of satyrine butterfly found in South and Southeast Asia.
Hypolimnas bolina, the great eggfly, common eggfly, varied eggfly, or in New Zealand the blue moon butterfly, is a species of nymphalid butterfly found from Madagascar to Asia and Australia.
Graphium nomius, the spot swordtail, is a butterfly found in South and Southeast Asia that belongs to the swallowtail family. The species was first described by Eugenius Johann Christoph Esper in 1793. One of the grandest sights is a host of spot swordtails mud-puddling or swarming around a flowering forest tree.
Papilio (Chilasa) agestor, the tawny mime, is a swallowtail butterfly, native to Indian subcontinent and widely found across Asia. The butterfly belongs to the mime subgenus, Chilasa, of the genus Papilio or the black-bodied swallowtails.
Papilio clytia, the common mime, is a swallowtail butterfly found in south and southeast Asia. The butterfly belongs to the subgenus Chilasa, the black-bodied swallowtails. It serves as an excellent example of a Batesian mimic among the Indian butterflies.
Papilio (Chilasa) slateri, the blue striped mime, is a swallowtail butterfly found across south and south-east Asia. The butterfly belongs to the mime subgenus, Chilasa, of the genus Papilio, the black-bodied swallowtails. The nominate subspecies is found in India and is also called the brown mime. It is a good example of mimicry among Indian butterflies.

Tirumala tumanana is a butterfly species within the Danainae subfamily of the family Nymphalidae. The butterfly is found in the extreme southern regions of the Philippines, including Sarangani and Balut Islands, as well as parts of Mindanao. It was first described by Georg Semper in 1886 based on specimens collected from Tumanao on Sarangani Island, located in the southern Philippines. Although Tirumala tumanana was originally considered a subspecies of Tirumala choaspes or Tirumala limniace due to its morphological similarities, recent studies focusing on male genitalia, wing patterns, and androconial organs have established it as a distinct and geographically isolated species.
