Not sure if this small butterfly is more blue or grey-browns on the inside of it wings, but it does have hints of pale blue along the edges where they run in line with, and close to, the body (photo1). There are various fawn & grey brown markings, on the underside of both wings, and what appears to be a frequently broken off-white line on the outer-most top perimeter of all wings. I’m inclined to think it falls into the ‘Blues’ category of butterflies, and would hazard a guess at a Speckled Line Blue (Catopyrops florinda).
