Dragonflies with waxy coating better able to resist a warming climate, research suggests

A trio of biologists at the University of Colorado has found that dragonflies that cover themselves in a waxy coating fare better as the climate grows warmer and drier in regions where they live. In their study, published in the Proceedings of the National Academy of Sciences, Michael Moore, Sarah Nalley and Dalal Hamadah tested the impact of pruinescence in two ways with dragonflies living in dry parts of North America.
