Rare big Butterfly perched on whit cushion

I was shocked this morning when I see there is a big butterfly perch on the cushion that I put near to my store room, this butterfly seem lost and trap into my house, so I take my smart phone and start taking some picture of thia rare butterfly

Normally this kind of butterfly can easily be found within the forest, but unfortunately this creature lost his signal and trap in my house

The abnormal shape makes me a bit doubt to get close to the butterfly so I maintain the distance, so I can have the proper angle to take it.

BEST REGARDS,
