Insectageddon

Even in a protected rain forest, with no pesticides, insect diversity has crashed in the last few decades. A light trap used to photograph 3,000 species in one evening. The same light trap, operated nowadays in the same way at the same season, now records a small population of few species.

Sharp population decreases are also observed in animals that eat insects.

Scientists suspect the damage is done by ecological mismatches caused by changed aspects of the climate in each place. If so, to avoid disaster we need to stop the global heating that causes the other changes.
