Small butterfly (15-18 mm) which is dimorphous sexual. The male upperside is pearly blue with dark grey borders and a grey point to the subsequent submarginal line.

Both have wings fringed with a white stripe interspersed thin black lines forming a white checkerboard. The caterpillars have a dorsal gland which secretes a sugary substance of high energy content.
