Description
It resembles the Monarch butterfly (Danaus plexippus) of the Americas. The caterpillar of the Common Tiger butterfly obtains a supply of poison by eating poisonous plants, which makes the caterpillar and butterfly a distasteful morsel for predators. A study in Northeastern India showed a preference to foraging on Crotalaria juncea compared to Nerium oleander, Barleria cristata rosea and Bauhinia perpurea (Bhuyan et al. 2005).

Wingspan 75-85 mm. The sexes are similar. The wings are tawny with heavy black markings along the veins; this butterfly is called the Striped Tiger in India. The scent patch on the male is oval and is located on the second vein of the hind wing.

The upper side of the apex of the forewing is black. Below the apex, a row of elongated white marks forms a loose band across the wing. The black marginal band on the underside of the hind wing has two rows of small white spots. On the upper side, the corresponding inner row is often incomplete.

Adaptations for Survival
The Danaids also have many other marvelous adaptations for survival. For instance, the larvae often feed on plants containing poisons and unpalatable substances. Instead of eliminating or detoxifying these chemicals, they assimilate them in their haemolymph (body fluids). These substances are then passed on to the adult butterflies through the pupal stage. As an adult, the male also assimilates poisons from plants such as Heliotropium indicum and Crotalaria pallida. When captured, its first line of defense is to emit nasty smelling chemicals that encourage the predator to release it - the extrusion of the 'Hair Pencils' is a common observation. The butterfly also shams death when captured - most avian predators will not consume a butterfly that is already dead. If captured and swallowed, the chemicals of the butterfly act quickly to induce vomiting in the birds. The poisons themselves are never found in lethal concentrations but in amounts sufficient to leave a lasting impression on the predator - perhaps an education that may be passed on to their progeny.

In addition, because of their tough and leathery bodies, Danaids are difficult to kill and have a remarkable ability to fly away after a bird has tried to eat them. These adaptations make these butterflies quite unattractive to predators. Young inexperienced birds catch these unpalatable insects from time to time, but then realizing that they are not good to eat, they release them without much harm to either to themselves or the prey. The confidence of these butterflies in their chemical defenses are well reflected in their nonchalant leisurely flight.

Hi Jitti

A very beautiful macro shot from you!
I like your close composition here because it really concentrates all the attention at this splendid butterfly.
The side POV is also great for it allows a good angle for the pattern of the under-wings and the exceptional sharpness level really gives us some impressive details for these parts.
Charming colors and good lighting, too.

Bravo and TFS
Horia

Fantástica nitidez y maravillosos detalles.
La luz es fantástica para crear este ambiente que rodea a la mariposa.
Una nota estupenda, muy completa.
Saludos Jitti.
