Flies grow bigger up north: Insect size a promising new proxy for palaeoclimate

Scientists use many proxies to reconstruct Earth's ancient climates. Pollen, diatoms, geochemical isotopes and fossils, for example, all contribute to piecing together past-climate puzzles. The ubiquity and wide geographic range of insects—like the nonbiting midge (Order Diptera, Family Chironomidae), a type of fly—have made them a useful tool to reconstruct palaeoclimates around the world during the recent geologic past.
