Blue Tiger

I would agree with subspecies exoticus now, sorry for the confusion.

Leopardus=Leopard= Panthera pardus kotiya
so we call him blue leopard

@Ornithoptera80 Thank you

Thank you for the information Ornithoptera80! Subspecies are something that always confused me :)

Ornithoptera80, is there a notable difference between sub-species in butterflies? Asking for my knowledge...

Sri Lanka subspecies is Tirumala limniace leopardus

Look at the small 'V' shape in the hindwing. Glassy tiger doesn't have that.
Check this, https://www.projectnoah.org/spottings/26....

but the butterfly is smaller than regular blue tiger
