Thousands of species

Although many people overlook them, moths are numerous and widespread, with over 2,500 species in Britain living in a wide range of habitats. They are a major part of our biodiversity and play vital roles in the ecosystem, affecting many other types of wildlife.

Why are they in decline?

The reasons for the loss of moths are many and complex. The loss of habitats resulting from more intensive agriculture, commercial forestry, industry and urban development are likely to be major reasons. A large factor is the changing climate. But it is possible to change this!
