Summary
Dr Erica McAlister uncovers a treasure trove of remarkable insights from the insect world including the innocuous flies that are Drosophila melanogaster. More is known about these flies than any other animal on the planet, as a model for human genetics. And the hoverfly that arguably undergoes the biggest transformation of any animal and how insect metamorphosis could be a tool to track future climate change.
