description Silver-studded Blue Overview
The Silver-studded Blue (Plebejus argus) is a butterfly species belonging to the Lycaenidae family, widely distributed across heathlands and grasslands in Europe. It derives its common name from the distinct metallic silver spots found on the underside of its hindwings. The larvae possess a specialized myrmecophilous relationship with ants, secreting a sugary substance that the ants harvest while offering protection to the caterpillars. This mutualistic behavior is essential to the butterfly's survival and reproductive cycle.
