insect populations, which are naturally variable, with wide, trend-obscuring fluctuations from one year to the next.

Half of all farmland birds in Europe disappeared in just three decades.
“it is not only the vulnerable species but the flying-insect community as a whole that has been decimated over the last few decades.”

Only about 2 percent of invertebrate species have been studied enough for us to estimate whether they are in danger of extinction, never mind what dangers that extinction might pose.
