When to seeJune to August
AboutThe silver-studded blue emerges in June and is usually on the wing until late August. It is a rare butterfly, generally found in heathland habitats that have shorter, sparsely vegetated areas. It is restricted to close-knit colonies in southern England and Wales. Two subspecies can be found in its range, while two others are now extinct in the UK. The larvae feed on a wide variety of plants, such as Bell Heather, Cross-leaved Heath and gorses.
How to identifyThe silver-studded blue is a small butterfly which gets its name from the light blue reflective 'studs' (scales) found on the underside of the wings. The upper wings are blue with a dark outer rim. Males are bluer than females, which are more of a dull brown.
In our area
In Shropshire, we have the only site in the West Midlands where the endangered silver-blue butterfly can be found. Prees Heath Common Nature Reserve near Whitchurch has been restored to open heathland for the butterfly and can be visited by the public throughout the year. The site was used for warfare training during WWI and as a bomber airfield during WWII. The old aircraft control tower is still present and provides a reminder of part of the areas past history. Following a public appeal which Shropshire and Cheshire Wildlife Trusts were both involved with, the site was bought by The Butterfly Conservation. Shropshire Wildlife Trust have bought the adjoining site Prees Heath East - this extension has been purchased to act as a satellite site for the butterfly, supplying additional suitable habitat for them to thrive in.
