This small butterfly is found mainly in heathland where the silvery-blue wings of the males provide a marvellous sight as they fly low over the heather. The females are brown and far less conspicuous but, like the male, have distinct metallic spots on the hindwing. In late afternoon the adults often congregate to roost on sheltered bushes or grass tussocks. The Silver-studded Blue has a restricted distribution but occurs in large numbers in suitable heathland and coastal habitats. It has undergone a major decline through most of its range.
Stable or increasing in some places, declining elsewhere.
The larva are dependant upon being "farmed" for sugary secretions by ants and will ussuall die if not tended and cleaned by the ants.
