Caption: Entomologist Claudio Gratton and limnologist Jake Vander Zanden (background) survey a stark grassy landscape amidst a swarm of gnat-like bugs known as "midges." The University of Wisconsin-Madison scientists venture into remote parts of Iceland to explore how midge swarms might embody a unique ecological connection between aquatic and terrestrial ecosystems.

Caption: UW-Madison scientists are using large plastic buckets (shown here) to trap gnat-like bugs known as "midges" that periodically rise up by the trillions to form thick, hovering swarms. Led by UW-Madison entomologist Claudio Gratton, the researchers venture into remote parts of Iceland to explore how midge swarms might embody a unique ecological connection between aquatic and terrestrial ecosystems.
