Source link Scientists have been looking into insects, particularly butterflies, in recent news. Entomologists, scientists who study the ecology, behavior, and physiology of insects, have found that butterflies play an important role in the environment.

In research published in May 2021, entomologists surveyed different species of butterflies across four European countries. They found that butterfly populations have declined dramatically since the 1990s, with some species showing declines of up to 85 percent. This could have a significant impact on the environment, with butterfly populations acting as pollinators, an essential part of the natural food chain.

In response to this alarming news, the European Union (EU) released the Biodiversity Strategy for Europe in May 2021, which aimed to protect species and habitats. This plan includes protecting at least 30 percent of all land and ocean areas, increased investment in conservation and restoration, and integrating biodiversity into economic policies. The EU also plans to invest €3 billion in the Action Plan for Nature, People and the Economy by 2020.

In a study published in April 2021, researchers from the University of Illinois examined how butterflies’ vision is affected by changing coloration due to climate change. The study found that butterflies’ color vision is sensitive to the color of the environment. The researchers suggest that with these findings, scientists can understand how climate change is affecting butterflies, and ultimately lead to solutions to mitigate the effects.

Overall, recent studies have revealed new insights into the importance of butterflies and their role in the environment. In addition, as more research emerges on the impact of climate change on butterflies, scientists can continue to develop strategies to conserve and protect these important species.
