Founded in 1982, the Upper Thames Branch aims to protect butterflies, moths and their habitats in the counties
of Berkshire, Buckinghamshire and Oxfordshire. The Chiltern Hills, the Oxfordshire/Berkshire Downs, the Oxford
and Aylesbury clay vales, the Bernwood Forest complex, the edge of the Cotswolds and the Berkshire heathlands
are all to be found in the three counties. Several rare species of lepidoptera can be found in the region,
including the Black Hairstreak, Adonis Blue, Silver-spotted Skipper and Duke of Burgundy butterflies, and
the Striped Lychnis and Heart moths. |
