The butterflies that are light in colour and dragonflies can easily adjust themselves in the changing climate, a new study has found.
The researchers observed that the butterflies and dragonflies of light colour were found in big numbers in hotter parts of Europe.
According to the scientists, with the increasing global warming and degrading climatic conditions, the weather is getting warmer across Europe.
While the insects of lighter complexion easily adapted themselves in the warmer regions, the darker colored butterflies were noticed moving to cooler areas. According to the scientists, this change in habitat has been witnessed over the past decade. They also think that this pattern is likely to continue as the climate is getting warmer.
The light-colored butterflies were also found to be shifting their geographical range towards north, the researchers said.
There is a common theory in science that says darker objects absorb sunlight more. This may be the most probable reason for the migrating behavior of the darker coloured insects.
To find the reason behind the migration of insects, the researchers conducted a study. During the study, the researchers observed different locations of insects across Europe for a period of 18 years and then found light insects survive better in hotter climates.
The study findings established the common scientific theory mentioned above. The researchers say an insect’s color reveal a lot about the amount of energy it has absorbed from the sun and it in turn influences body temperature.
