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.

How do bumblebees fly?

Greetings readership,

The flight of the bumblebee is not only an excellent classical piece composed by Rimsky-Korsakov, but also the subject of another ‘fact’ about insects, which usually goes something like: “According to the laws of physics, bumblebees shouldn’t be able to fly.” or a phrase of similar meaning. 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!

Public perceptions towards insects and allied taxa: why are so many people afraid of them?

Greetings readership.

Public perceptions of the vast majority of insects and terrestrial arthropods tend to be fairly negative. Indeed, the word “insect” alone can elicit a visceral response in some. Attitudes towards insects in the general public of many developed countries are dominated by Fear, where many people are afraid of insects, and Power, where they may want to control insects (The Buzz of Insects, 2007).

Fear may arise from psychologically intrinsic characteristics of humans that were adapted initially to avoid dangerous arthropoid (arthropod-shaped) species. In addition, negative views may arise, or be reinforced, by cultural cues from peers and parents, teachers and authority figures (i.e. learned). Using myself as an example,
