Insect flight – an evolutionary development that shaped the world

Flying animals have had a major impact on nonflying organisms. Briefly consider the ecological and evolutionary interrelationships between pollinators and flowers, or between mosquitoes, the parasites they transmit and humans. Even a cursory glance at the manifold relationships flying insects have with all other forms of terrestrial life evaporates any doubt whether the world would be a very different place if they had never evolved.

Indeed, the violation of the observably consistent Newtonian Laws of Motion by bumblebees and only bumblebees is not a very strong position to hold and might suggest the advocate of this belief should more fully examine how bumblebees generate lift. I shall try to provide such an examination. But first, let us delve into insect flight more generally!
