<p>This great close-up footage shows a summertime scene of a swarm of buzzing mosquitoes in the Alaskan arctic tundra. Recorded by ecologist Shannan Sweet, she told us how area natives described this swarm as the worst they had ever seen. The local population of the bloodsucking insects has swelled this summer due to heavy rain, which followed an unusually heavy snowfall last winter. Credit: YouTube/Shannan Sweet.</p>
