Moth studies shedding light on global insect declines

Source: butterfly-conservation.org

Moths are the most taxonomically and ecologically diverse insect taxon for which considerable abundance and distribution data exist in various parts of the world. A new paper by the universities of Connecticut and Nevada, in collaboration with Butterfly Conservation, presents new analyses of caterpillar abundance data for Arizona (USA), Costa Rica and Ecuador, and reviews the global evidence for moth biodiversity change1.

The world is facing a biodiversity crisis with an estimated one million species threatened with extinction2. However, the trends of insects, which make up at least 60% of all species on Earth3 and contribute vital and valuable ecosystem services, such as decomposition, pest control and pollination, remain poorly understood.
