Dragonflies adapt wing color to temperature

[Still Waters]

New research from Case Western Reserve University in how dragonflies may adapt their wing color to temperature differences might explain color variation in other animals, from lions to birds.

Further, the findings could also provide evolutionary biologists clues about whether rising global temperatures might adversely affect some species.

"People have long been aware of variation in dragonfly wing color, but what we are showing in this new work is an overlooked environmental factor—how temperature affects coloration," Martin said. "This could turn out to also determine some of the really cool extravagant traits we like to look at, such as coloration in birds."
