About 70 per cent of the species on Earth are insects. They are fundamental components of most ecosystems: they comprise half of the biomass on the planet, pollinate flowers, decompose dead organic matter and play multiple roles in food webs. They are quite literally everywhere, including in and around our homes, but they have also been declining at alarming rates in many places.
The societal implications of this potential “insectageddon” could be catastrophic, including losses in human food production. However, confirming suspicions of global declines is difficult because we lack reliable data on insect populations in many parts of the world.
