- Recent studies from Germany and Puerto Rico, and a global meta-study, all point to a serious, dramatic decline in insect abundance. Plummeting insect populations could deeply impact ecosystems and human civilization, as these tiny creatures form the base of the food chain, pollinate, dispose of waste, and enliven soils.
- However, limited baseline data makes it difficult for scientists to say with certainty just how deep the crisis may be, though anecdotal evidence is strong. To that end, Mongabay is launching a four-part series — likely the most in-depth, nuanced look at insect decline yet published by any media outlet.
- Mongabay interviewed 24 entomologists and researchers on six continents working in over a dozen nations to determine what we know regarding the “great insect dying,” including an overview article, and an in-depth story looking at temperate insects in the U.S. and the European Union — the best studied for their abundance.
- We also utilize Mongabay’s position as a leader in tropical reporting to focus solely on insect declines in the tropics and subtropics, where lack of baseline data is causing scientists to rush to create new, urgently needed survey study projects. The final story looks at what we can do to curb and reverse the loss of insect abundance.
In recent months a debate over whether a global insect apocalypse is underway has raged in the mainstream media and among researchers. To assess the range of scientific opinion, Mongabay interviewed 24 entomologists and other scientists working on six continents, in more than a dozen countries, to better determine what we know, what we don’t, and, most importantly, what we should do about it. This is part one of a four-part exclusive series by Mongabay senior contributor Jeremy Hance. Read Part II, “Vanishing act in Europe and North America” here.
Dust stirred up by the wind turns a Kenyan sunset deep scarlet. Then, as day fades to night, millions, maybe billions, of insects, fly to the artificial lights of homes found at the edge of the bush. One of those residents is Dino Joseph Martins, and while his evidence is anecdotal, the entomologist is a highly qualified observer. Martins has vivid recollections of a time when the abundance of insects swirling around the lights illuminating his outdoor dinner table were staggering.
“You would struggle to sit down to eat your supper because you would have endless beetles and [flying] things falling in your bowl of soup,” he said. Today, “that happens far less.” Now, dinner in the African bush may be a pleasanter affair, but it’s much more disquieting.
Martins, the executive director of the Mpala Research Center, was born and raised in Kenya. As a child, he recalls visiting forests during the wet season that were filled with “tens of thousands of butterflies and other things lining the paths and the roads.” He says you can still find the same kinds of insects in those same forests nowadays, “but in far, far fewer numbers.”
“I just wish we had collected [abundance] data more robustly earlier on, which we hadn’t done,” says Martins. This dearth of baseline data on insect abundance, everywhere around the globe, lies at the heart of an urgent question: is the great insect apocalypse underway, or not? And if it is, how bad is it, where is the crisis most acute, and how can we best respond?
“Now, of course, we should start,” Martins adds. “That’s where we are at.”
