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.
The ‘well-known fact’ that “If a flea were the size of a human, it could jump over the Eiffel Tower” is an interesting misconception – one that disregards laws of scaling and structural engineering. A brief analysis of the claim can reveal some of its substantial flaws. But before we go any further, let’s use our imaginations, if only as a preliminary thought-experiment.
Picture a human-sized flea (let’s say about 170cm in length), henceforth named ‘enormo-flea’. It has the exact same proportions as an ordinary flea, but happens to be 170cm long.
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,
Here we have the final scholarship essay, soon be published in the Royal Entomological Society’s members’ magazine, Antenna. Its author is Siobhan Anne-Marie Hillman. She developed her love of entomology whilst studying at the University of Derby, graduating with a BSc in Zoology. Siobhan’s main interests are in Continue reading →
Below awaits another scholarship essay from a student studying the Entomology MSc here at Harper Adams Univsersity, soon to be published in The Royal Entomology Society’s members’ magazine, Antenna. But before that, a little detail on our ongoing module Biology and Taxonomy of Insects. Continue reading →
Friday brings us many things. Many good things (besides the end of the week).
Today, the students taking the Biology and Taxonomy of Insects module on the Applied Ecology suite of MSc courses here at Harper Adams University were treated to a day consisting entirely of Hymenoptera-related (wasps, bees and ants) lessons, from Dr Andrew Polaszek, of the Natural History Museum (NHM) in London. Starting the day off with an overview of the Order, Dr. Polaszek went on to characterise the super-families using morphological and ecological definitions. The class later went on to try our hand at the initially daunting task of identifying specimens to super-family, family or genus level based on various keys. The fact that the majority of students were able to identify the specimens shows the quality of the keys and the direction Dr. Polaszek gave to us. By the end of the afternoon, most students had been identifying specimens for 2h30m, with the majority actively enjoying the process, and improving over the course of the day. Continue reading →
With another day, comes another Antenna scholarship essay for you to read. This one is from a highly knowledgeable colleague, Jack Cox, who completed his BSc in Zoology at the University of Derby. Specialising in orthopterans, Jack has a particular interest in their taxonomy and behavioural ecology, aspiring to eventually conduct scientific research and have his work published. Keen on the idea of a PhD, he’d also be happy to work in industry or to eventually become a lecturer (if any readers would like to offer an opportunity to Jack *hint hint* you can contact him on firstname.lastname@example.org).
