Save Mayflies and the Ecosystems that Depend on Them

(Beyond Pesticides, February 3, 2020) In more bad news from the insect world, recent research published in the Proceedings of the National Academy of Sciences reveals a precipitous decline in numbers of mayflies where they have been historically abundant. The research finds that in the Northern Mississippi River Basin, seasonal emergence of burrowing mayfly (genus Hexagenia) adults declined by 52% from 2012 to 2019; in the Western Lake Erie Basin, from 2015 to 2019, the reduction was a shocking 84%. Neonicotinoid insecticides are a significant factor in this decline because mayflies are extremely vulnerable to their impacts, even at very low exposure levels. Ask Congress to tell EPA, USDA, and the Department of Interior to develop a joint effort to ensure that its decisions and compliance with its authorizing statutes address the crisis of the threat to mayflies. Ephemeroptera to entomologists—“mayflies” to the rest of us—is an insect order comprising keystone species, on which other species in an ecosystem are very dependent, and without which, the ecosystem would undergo drastic change. The plummeting mayfly “count” is especially alarming because mayflies are a critical, primary food source in aquatic and terrestrial ecosystems, and provide an important ecological service. As the research study notes, “Seasonal animal movement […]
