Study shows insect declines on land but recoveries in freshwater

A worldwide compilation of long-term insect abundance studies shows that the number of land-dwelling insects is in decline.
On average, there is a global decrease of 0.92% per year, approximately 24% over 30 years.
The number of insects living in freshwater, such as midges and mayflies, has increased on average by 1.08% each year.
Results come from the largest study of insect change to date.
