In every stage of their lives Lepidoptera fall victim to a host of predators, parasites, diseases, and destructive practices. They are a very important link in the food chain, and even beneficial insects like Green Lacewings and Ladybugs will feed on eggs and tiny larvae. Those losses are natural and part of the chain. But, it has been estimated that by far, humans have taken the greatest toll on Lepidoptera populations. Destruction of their habitat without replacing native species or substituting more cultivated varieties, and blanket use of pesticides are practices that could easily be changed without too much inconvenience.
