Bangkok...

This beautiful butterfly elected to spend the night at home.

Quite large: the wingspan is 19 cm.

Can somebody identify it?

Sorry can't identify it, but I think you will find that it is a Moth?

yeah look very much like a moth, but a nice one ..

this animals are commonly kinda big around here.

i did see one sleeping in the parking lot with almost same span size

also butterfly's can get kinda huge here like this one: http://goo.gl/oxCB6

It is a Thai BMF moth. Very common.

This, my dear Krungbin, is a member of the Uraniidae family (Uraniidae Uraniinae).

The moth in question is commonly known as Lyssa Zampa.

Many thanks, my dear Forethat! What a beautiful animal!

Actually, that looks like an Atlas Moth (worlds largest moth). How heavy was it?
