3 out of 4 animals on our planet are insects. Spread over approximately 1 million species, these are unique indicators of biodiversity. Their adaptation to all diets gives them a prominent place in both ecological balance and economic life: 70% of flowering plants in the world depend on pollination by insects. Scientists estimate that 70-97% of insect species still remain to be discovered. The pressure of human activities on the environment is such that it can be expected that many will have disappeared before they have even been described.
