The decline of moths globally: a review of possible causes.
The dramatic increase in decline of moths constitutes a great threat to ecosystem, leads to biodiversity crisis of moths. Loss of moth diversity has been inadequately quantified because of nocturnal nature of moths. The substantial decline of moths has been reported in various countries such as U.K, U.S, Germany, Sweden, India, Netherlands, Siberia and New Zealand. 31%, 44%, 27% and 71% of moths declined in Great Britain, Southern Britain, Sweden and Netherlands respectively. Collapsing of moths is a prime concern, because they serve as food for wide range of taxa, such as birds, bats, spiders and reptiles. While as, moth larvae are fed on by insects, bacteria and fungi. The various major potential drivers responsible for causing dwindling of moth population are destruction of habitat, climatic change, intensification of agriculture, urbanization, chemical pollution, artificial light pollution and invasion of non-native species. In this article, overall review on the global decline of moths is discussed, including the preventive measures and future perspective.
