The GREY PANSY Butterfly, spelled Gray in USA, is native to the Indian subcontinent and Southeast Asia.
The background is often more light brown than grey.
Whether light brown (above left) or grey (above centre and right), it has brown wavy lines and orange and black eye-spots on fore and hind wings.
The brown pansy butterfly is not a Brown Pansy but a Grey.
Side view: the pansy on the lemon is not a Lemon Pansy.
A tattered individual in Singapore.
