On August 21, 2017, millions of people across America stopped what they were doing to observe a total solar eclipse. But a new study suggests humans were not the only living beings who took a break from their usual activities during this historic event. A total solar eclipse happens when the sun, moon and Earth perfectly line up. Last year’s total solar eclipse was the first one in 99 years to pass over parts of the whole United States. The new study found that bees went silent when within the path of totality of the solar eclipse. The results were recently published in the Annals of the Entomological Society of America. The research was led by Candace Galen, a professor of biological sciences at the University of Missouri.
