Climate warming favors light-colored insects in Europe

Studies show that climate change butterflies and dragonflies with a lighter shade of color do better in warmer areas of Europe. It gives them an advantage over the darker insects when faced with climate change. Colleagues from the University of Copenhagen and Imperial College London, showed a clear pattern of light-colored insects dominating the warmer south of Europe and darker insects dominating the cooler north. Ultimately, they showed that for dragonflies, the insect assemblage in Europe has, on average, gotten lighter during the last decades

 Lizards and snakes absorb energy from the sun that allows them to become mobile. The darker their color, the more sunlight they can exploit. Therefore it makes sense to see darker insects in cooler climates. Researchers were surprised to find such a distinguished color pattern between the northern and southern species, since the surface colors also serve many other purposes.

NOS THEMES
Science is collaborative: Many researches worked together and pooled their data into one.
Science is based on evidence: Through observations, researches have been able to make out the certain characteristics of insects.Which ultimately became evidence to support their hypothesis.
