Climate change driving moth decline in Scotland, study finds

Climate change and habitat destruction have led to a major decline in moth numbers in Scotland, according to a study from Scottish Natural Heritage (SNH).

The study, published today, found that moth abundance has fallen by almost 50% over the last 25 years, with more species classed as ‘significantly decreasing’ than ‘increasing’.

Eight of the 20 species in most rapid decline are associated with moorland, which indicates that the insects may be disproportionately struggling in this habitat, according to SNH. However, SNH says the figures also suggest that common woodland moths may be doing well in Scotland.
