Not long ago, a lengthy drive on a hot day wouldn’t be complete without scraping bug guts off a windshield.

It’s a symptom, they say, of a vanishing population. “The windscreen phenomenon is probably one of the best illustrative ways to realize we are dealing with a decline in flying insects,” said Caspar Hallmann, an ecologist at Radboud University in the Netherlands. Hallmann is part of a research team that recently waded through 27 years’ worth of insects collected in German nature preserves. “This decline happened in nature reserves, which are meant to preserve biodiversity and ecosystem functioning,” Hallmann said. “This is very alarming!”

“If you like to eat nutritious fruits and vegetables, you should thank an insect. If you like salmon, you can thank a tiny fly that the salmon eat when they’re young,” Black said. “The whole fabric of our planet is built on plants and insects and the relationship between the two.”
