For insects in Europe, climate change has led to habitat change. In the past couple of decades for example

Mediterranean butterfly and dragonfly species. have been found flying around places previously off limits to them.

New northern climbs such as Germany.

Now... such as Germany. Germany. Now a study in nature communications finds a colorful reason for the northern expansion.

As northern Europe warms, the light colored butterflies and dragonflies typically found in the Mediterranean find themselves able to survive in the newly warmer north and to even outcompete their darker-colored rivals.

Lighter colors reflect sunlight, while dark colors absorb it and heat up.

Hence chocolate ice cream melts in the sun faster than vanilla.

Lighter-colored insects thus function well in warmer climates.

They don't overheat as easily and can stay active longer, giving them a leg up,

well six legs up in our warming world. The researchers say this

migration of insects shows that climate change isn't something that's coming.

It's already happening and it could drastically affect which insects end up where, which will in turn affect us.

Thanks for the minute. For Scientific Americans 60 Second Science, I'm to follow me.
