So named due to the silvery blue metallic spots on the underside hind wings. The upperside are a rich, deep iridescent blue in the males with a black border and the characteristic Lycid white fringe. on the hindwings there is a row of inconspicuous black spots along the bottom edge. Females are dark brown with orange spots at the edges. On some sites the female has blue colouration but never as extensive as the male and she always possesses the orange spots. The undersides are a typical "Blue" design. The ground colour is silvery grey with blue suffusion at the base of the wings in the male and brown in the female. There are a number of black spots, each outlined in white and a row of orange spots along the outer edge of the hindwings, extending onto the forwings in the female. It is next to these orange spots that the "silver-studs" can be seen. Most easily confused with the Common Blue, it is generally slightly smaller and in the male the blue is a darker shade. The Common Blue also has an additional black spot at the base of the underside forewing. It has suffered severe reduction in its range in the UK due to habitat destruction. Its favoured habitat is heathland and where it is found in the southern strongholds it can still be very numerous. Other habitats include calcerous grassland and dunes. Apart from its strongholds in the southern heathlands it is also found in scattered colonies in Norfolk, Suffolk, Devon, Cornwall and Wales. It is still widespread and locally common across Europe, Asia as far as Japan.
