Challenging times are ahead for smaller, lighter-colored butterflies as Earth’s climate continues to warm, a new study has found
. Unlike their relatives with larger wings and darker colors, small butterflies with paler hues — particularly those belonging to the Lycaenidae family — have trouble regulating their body temperatures as the air temperature increases, according to the research.
Each one was held in a glass jar set up to keep the butterfly from dehydrating. Then the temperature was steadily raised inside the jar to test how much each could stand before falling after losing motor control, a state known as “knockdown.” In both experiments, dark butterflies the researchers captured warmed up and cooled down better than their paler relatives.
