Silver-studded Blue Plebejus argus

The Silver-studded Blue (Plebejus argus) is one of Suffolk’s most celebrated insects. The county’s Sandlings heathlands support nationally significant populations, making Suffolk a crucial stronghold for this declining butterfly. Adults are on the wing in July and August, the males a vivid violet-blue, the females a warm brown. The species has a remarkable relationship with black ants, which tend the larvae and assist newly emerged adults. Key Suffolk sites include Dunwich Heath, Westleton Heath, and several RSPB-managed reserves. Heathland restoration and sensitive grazing management are essential to its continued presence in the county. Image: © elec_o, iNaturalist
