Silver-studded blues live in the dune heath fields of Terschelling, Texel and Schiermonnikoog. The wings of the male are blue from above while those of the female are brown. The silver-studded blue lays its eggs on heather and cross-leaved heath. It lives in transition zones between wet and dry terrains. The caterpillars pupate in ant nests. Silver-studded blues are on the Red List for threatened butterfly species.
