[Note Guidelines] Photographer's Note
I had some trouble identifying this butterfly. It appears close to either the Dark Blue Tiger Tirumala septentrionis musikanos or the Blue Glassy Tiger Ideopsis vulgaris macrina , both found in Sri Lanka. Several other tiger species are similar in appearance.
Both species are Danaids. The Danaid larvae often feed on plants containing poisons and unpalatable substances. Instead of eliminating or detoxifying these chemicals, they assimilate them in their body fluids and retain them as adult butterflies. The male adult also assimilates poisons from plants such as Heliotropium indicum and Crotalaria pallida.
When captured, the insects first line of defense is to emit odorous chemicals that encourage the predator to release it. The butterfly also shams death when captured - most avian predators will not consume a butterfly that is already dead. If captured and swallowed, butterfly toxins act quickly to induce vomiting in the birds. The poison concentration is sublethal, but leaves a lasting impression on the predator.

Because of their tough and leathery bodies, Danaids are difficult to kill and have a remarkable ability to fly away after a bird has attacked. Source.

Excellent shot, Greg.
The exposure is just perfect, exposing gorgeous colors and markings.
Crystal clear details well shown against a nicely blurred BG.
TFS. ; )

Hi Greg, I think you have identified the butterfly correctly. It is a great photo with very nice exposure and color. Focus is outanding. I can see the texture in the wings. Looks great! Ken

Hello Greg
Beautifull butterfly - it's really pity that there are no butterflies like that in Europe ;-)
