Butterfly Conservation was formed by a small group of dedicated naturalists in 1968 following the alarming decline of many beautiful butterflies and moths, a decline that the society aimed to reverse. Our vision is of a world rich in butterflies and moths for future generations to enjoy. Butterflies are beautiful and intrinsically valuable. Together with moths, their sensitivity to environmental change makes them valuable indicators of the health of the countryside.
46 species of butterfly can be found in Hampshire and the Isle of Wight. In any year, between 30 and 40 of these species can be seen on our reserves.
Around 1940 species of moth have been recorded in Hampshire and the Isle of Wight, over 600 of these on our reserves.
Butterfly Conservation has over 25 reserves across the UK, including 3 in Hampshire: Yew Hill, Magdalen Hill Down and Bentley Station Meadow.For the foreseeable future the branch intends to publish an e-Newsletter every two months. For further information please click here.
