- A new study in PLOS ONE reveals a 76 percent reduction in Germany’s flying insect biomass over the past 27 years while another reports the country’s bird abundance has declined 15 percent in just over a decade.
- While the causes behind the insect decline haven’t yet been conclusively studied, the PLOS ONE study suggests agricultural intensification like increased pesticide use may be contributing to the decline.
- Neonicotinoid pesticides have been blamed for bee declines, and studies also link them to declines in aquatic insect communities. Many flying insects have aquatic life stages.
- More research is underway to better understand the causes and ramifications of such a big decline in flying insect biomass.
