Flies, two-winged flying insects that include everything from houseflies to mosquitoes to midges, are some of the least studied insects on the planet, which is surprising given that they’re among the most populous and varied. But associations with filth and blight, biting and pestilence, and crop destruction don’t make them very appealing. Balcombe wants to change that. Flies are fascinating, vital, and beautiful creatures. Flies are essential to the food chain, among the most common plant pollinators, and clean up rot and decay. They help solve crimes and heal wounds, and even unlock the possibility of insect sentience. Most famous for helping scientists study genetic inheritance via fruit flies, Diptera, it turns out, have far more to teach us. Balcombe also warns of the potential catastrophic effects of human actions on fly populations. Monoculture and pesticides are greatly reducing their numbers, but without flies, ecosystems will collapse. They may be pests, but flies deserve our respect and admiration. This is an excellent overview of what we know and what we’re discovering about flies.
