Fruit flies can be truly annoying when they are buzzing around your living room or landing in your wine. But we have much to thank these tiny nuisances for – they revolutionised biological and medical science.
Flies and mosquitoes both belong to Diptera, the group of insects that have only two wings (from the Greek di meaning two and pteron meaning wing). However, just as most people accept the bothersome as well as the positive traits of their friends, we shouldn’t judge flies for their negative behaviour alone.
We should open our eyes to their enormous economic and environmental importance, as entomologist Erica McAlister argues in her book The Secret Life of Flies. For example, many plants (including the cacao plant that gives us chocolate) rely on Diptera as pollinators. Or try to imagine a world without flies to decompose dead animals.
