Insects play critical role in ecosystems beyond just providing food, new research shows

Insects provide protection, sanitation and even shelter to vertebrates, making them a priority for conservation efforts

The study, published in Nature Reviews Biodiversity on Wednesday, sheds light on the various ways insects support vertebrates, ranging from birds and bats to reptiles, amphibians and mammals.
