The midges of Iceland's Lake Myvatn can be so thick, it can be difficult breathing without inhaling bugs. Árni Einarsson, the Director of the Myvatn Research Station and a co-author of the study, inspects midges on the grassy shore of Lake Myvatn.

Midges periodically emerge by the billions from Iceland's Lake Myvatn and blanket the lake and surrounding area. A study of the midges by University of Wisconsin-Madison zoologist Anthony Ives and his team is illustrating how even slight changes in ecosystems can tip the balance of nature. The team reported its findings in the March 6, 2008 issue of the journal Nature.
